pull in an explosive barrel and hurl it down at the two enemies pretty much right in front of you. Climb down the ladder one level, look for good stuff (especially behind the red container) and then drop down to the hopper. Ignore it and go through the door where another hopper awaits you. Approach it and briefly retreat once it jumps up.

[Snipers] Open some supply crates and go outside. Haste along the left wall, hiding from the sniper up ahead whenever possible. Then, once you are next to a truck and a trash bin, run behind another truck, then behind a car and finally rush towards the sniper. Beneath the window you are safe, so take your time and throw up a grenade. Open the supply crates. Carefully go around the corner where another sniper controls the street. Haste across the street into the room with the big windows. Break open a supply crate, leave the room and run on to the right, while strafing and jumping to hopefully avoid some of the sniper attacks.
Enter the left building; kill two headcrabs with the gravity gun and a super zombie in the dark area with the shotgun. Enter the bathroom for some medi kits. Head down the ramp and go over to the hurt rebel. Defend him against some zombies with the shotgun. Further down the water corridor are two super zombies. Either use either use the pulse-rifle or the shotgun. It depends on which ammo you can afford to use at the moment.
Go up the stairs to some zombies you can luckily ignore completely: A sniper on the left takes care of them. Once he's done with them, lob a grenade into the sniper's window. In case you keep missing, there is a grenade crate nearby. Move on to meet Barney, asking you to eliminate two snipers. They aren't visible at the moment, so walk up onto the roof to trigger them. One is at the end of the roof (go down one storey to get him) and your second victim is on the left, attackable from the roof (of course both of them are behind windows again).
Approach Barney, help him against two toxic headcrabs and follow him down a pile of rubble to a Combine console he manages to hack to open the path to a supply crate and two poisonous headcrabs (gravity gun).
[Big Bertha] Go outside to a small backyard and pull in an explosive barrel from the right. Hurl it up at two Combine and a Sentry Turret. Smash the supply crate and move on to see the true power of the Combine weapon you are aiming to destroy. Go down the stairs, destroy the hopper, use the gravity gun against the Sentry Turret on your left and destroy yet another hopper.
Outside you will have to tackle the super weapon: A devastating beam comes down at a certain spot every few seconds. This spot is always right at the point you are going to be at when the beam strikes. Since you can see where it will strike next, you can try to dodge it. When you see it in front of you, stop and go back a few feet, as the weapons also has a blast radius. Note that you are safe under a roof or any under solid object. Head for the container near the pit for some health and some cover. Then get back out, turn left and run over the rubble. Somehow you seem to be more safe here than on the street. Head for the door, enter the building and kill two Combine with the pulse-rifle.
After patching yourself up at the health panel, open the next door, wait for the beam to strike again and run outside, heading for the small bunker ahead, which is only lightly guarded. Ignore any other enemies on the right and just proceed ahead to the next building. Two Combine will leave it when you approach it and another one waits inside. Pick up some more stuff and leave on the right. Head for the museum or whatever it is to be safe from the super weapon, but on the other hand you will have to face four normal Combine and an elite Combine. You might want to consider using not only the pulse-rifle but also its secondary fire. Walk past the main entrance, pull a plug behind the force field and enter the museum.
[A Visit to the Museum] Open the left door. See those blue laser lines? These activate sunken Sentry Guns which observe a certain area after having been activated. This one, luckily, is rather harmless. Walk into the laser, step back and you should be fine. Roll a grenade at the Gun while it is up to destroy it. In a small room behind you are infinite grenades and two supply crates.
The main hall. Hurl a grenade at the Combine appearing behind the force field at the exit sign and finish them off with the pulse-rifle. Then break the blue lasers nearby and destroy the two Sentry Guns. The first one can be struck without entering its area of sight, but for the other one you have to swiftly go around the corner, throw the grenade and retreat. Eliminate two Combine in the dark.
Go up the stairs, pass by on the lasers and rescue some reinforcements. Then equip a grenade, break the lasers, quickly step around the left corner and toss a grenade into both Guns without them being able to even see you. Afterwards enter the room behind the Guns to find two wall panels and the first shield generator. Use the gravity gun as you did when Alyx lowered the shields on the square. Go back to face lots of Combine and an elite Combine coming up the stairs you already came up from. I highly suggest a well aimed secondary fire of the pulse-rifle.
Now search for a bridge near the stairs (not the one opposite of it), walk over it, take a right and enter a room you are about to get trapped in. Stay close to the various openings in the walls (patrol along all of them) to get a shot at some Combine behind them. After a while one of the doors is about to be opened. Hit the two hoppers with the gravity gun so they land near that door. Once the door is open, a few more Combine enter the room, getting a taste of their own hopper medicine. Finish them off with the pulse-rifle. Also watch out for the other door which will also be opened (not as obviously, though) by two soldiers. Move on, go through the lasers and do not destroy the guns. Instead bunny-hop towards them and wait in between them for them to cease fire. Then deactivate the generator, which also takes care of the Guns and restock at the health panel.
Go over to the other wing of the building (either via the bridges or via the main staircase), tell your squad to stay back and break another blue laser. Toss a grenade at the only Sentry Gun and hide behind the table until the grenade explodes. The Gun guarded some grenades and health.
Now again tell your squad to halt and enter a nearby room with lots of red lasers and a hopper at the entrance. Dispose of the hopper, jump onto the structure right in front of you, walk left past the first few lasers and hop onto the block up ahead. Turn right to jump over the next lasers. Get onto the round thing with the pipes sticking out, walk around it and jump onto the pipe at the wall. Your way leads up the shelf, onto the right shelf and then onto the big solid console nearby. The rest should be self-explaining over the pipes to the switch which turns off the whole security including the hoppers.
Destroy the last generator which triggers loads of Combine and elite Combine to spawn on the ground floor at the main hall. Throw down a few grenades and kill the survivors with the pulse-rifle. Follow Barney down through the exit passage, destroy three hoppers, use the wall panels and proceed to a Combine console, Barney is about to hack. Enter the newly opened gate, take out a Sentry Turret (gravity gun) and two Combine (pulse-rifle) to clear the way up to the roof.
[On the Rooftop] Simply run along the roofs, killing some Combine with the pulse-rifle (and taking cover, while your men keep fighting) until you reach a health panel and a suit energy panel. As you use these, a gunship takes off. Fire off your first three missiles from where you are at the moment and then head back to the beginning of the roof area. There is a missile crate and luckily the gunship stays rather close here so you can take it down pretty easily.
Stay near this crate for a while until you see a dropship coming from the right. Hit the strider down below to not get bored as you wait. The dropship drops three Combine and an elite Combine which will open the gate at the panels, rushing towards you. Staying close to the gate is pretty much suicidal on the hard difficulty setting, even if you use the hoppers, but staying near the missile crate allows for a good overview of the situation and the enemy position and it allows for the use of the missile launcher. Just wait for the enemies to come into reach and kill them.
Move on to near the gate and snipe at an enemy in a guard tower. Move on until you stand behind a container. Pull in the three supply crates, smash them, bunny-hop to the switch near them, activate it and hop back. This lowers the bridge over to a heavily guarded building where infinite enemies keep coming. Fortunately you also have just triggered four rebels to join you. Stay behind the container, waiting for the first three enemies to run over the bridge. After having killed them, get onto the bridge yourself and use the secondary fire of the pulse-rifle to kill three more enemies across the bridge. Now let your squad lead the way and use the secondary fire again upon reaching the other end. There shouldn't be much resistance left and as the Combine stop respawning as soon as you successfully cross the bridge, you can simply clear the rooms in close-quarter battles with the pulse-rifle. Drop down the stairs.
[War of the Worlds] Welcome to the spectacular battle against the striders. Run to the front porch of the museum where some rebels are already fighting against the striders. Fire off your first three missiles and run on into the pit up ahead. Walk through the canal, wait for the second strider to cease firing and quickly run out of the canal and up the rubble. Then take a left into the building where you can nab some missiles. Fire them off, leave the building through where entered it and head for the bunker in the centre of the plaza. Again, pick up some missiles and use them to finish the job.
Proceed to the big pile of rubble, search for a passage through it and restock at the missile crate. Take down another strider up ahead. Afterwards step back and witness the striders' true power: A new strider coming from the right fires its laser beam at the corner of the building, blowing a hole into it. First destroy the strider then search for a health panel inside. Get back and use the missile launcher against some Combine at a barricade down the street. Go there, walk down the stairs and smash some crates.
[Big House] Briefly step out onto the street to attract a Combine on your right. Retreat and kill him when he's gotten close to you. Then head down the street on the right, escaping into a basement on the left. Pick up the explosive barrel with the gravity gun to hurl it at three Combine coming through the doorway in front of you. Throughout this area new sentry drones appear, but as they can only pester you, first defeat any real enemies or take cover before dealing with them. Walk up the stairs while wielding the shotgun. Lure the two Combine down into the staircase to make the shotgun more effective. Enter the bathroom on the left for two supply crates; then pass up on the ramp to find three more crates. Walk up the ramp, shoot the crossbow at a Combine on the left and run over to the staircase to find some health. Leave the staircase and walk up the concrete bar in the centre of what used to be a room. Hide behind the debris as long as you need to safely run out and over to the next storey of the staircase. There's a missile crate here, but you absolutely don't have to defeat the strider outside. Only do it if you feel like. Anyway, the next step is to hop into the passage next to the crate, smash three supply crates and drop down.
[Big Battlefield] Hop down into the basement, smash a crate on the left and assist your allies in a fight against four Combine with the pulse-rifle. Smash another crate, run up and ignore both the strider and the elite Combine. Drop into the hole on the left and quickly head for the room up ahead where you will find cover and two supply crates. Go around the corner, hide on the right and wait for the second strider to pass by. Drop into the hole the strider came out of and prepare of the three elite Combine to catch up with you. Use the pulse-rifle against them. Break open a supply crate in the dark.
Move on until the ground below you is blown apart. Look up and use the secondary fire of the pulse-rifle against the right-most Combine. This should also take care of another Combine, only leaving one behind. Kill him, climb up, smash a crate and get outside. Take cover behind the various walls, eliminate some Combine above and run away from any grenades, but don't waste too much time here. Don't try to kill ever enemy; instead go around the corner, pick up some items, lean against the wall to hide from the strider and haste into the closed room nearby. Shoot a Combine with the shotgun and break open a few supply crates.
Go up, take down a Combine with the shotgun and definitely ignore the goodies nearby. If you get close to them, the strider in the background will fire off its big beam at you. Instead, drop down and keep fighting for a while until the strider opens a new path in front of you. Drop down, hide in the small room on the left where some crates wait to be cracked open and then haste out and up on the left. Kill a few enemies without stopping. Afterwards enter the building, look for some goodies on the left and walk up the stairs to the roof. Defeat another Combine and equip the missile launcher to battle the two striders. But before that, retreat into the staircase until the gunship flies off. Then ignore the Combine on the other roofs, restock at the missile crate, hide in between your attacks and whenever all of your squad members are dead, retreat into the staircase until you have some rebels at your side again, as these draw most of the striders' attention on them. Also don't refrain from patching yourself up at the health panels on the ground level whenever you need to.
After taking down the two striders, clear the roofs from the Combine, using the missile launcher. Hey, it's fun and you there's a missile crate nearby. Then balance over the girders at the side of the roof where the stairs end. Drop down behind the wall, kill a Combine, pick up some suit energy in a dead end on the left and move on, triggering D0g to appear. While he doesn't defeat the whole opposition, he at least draws the attention to him, giving you the chance to clear the area. Go to the barricade and drop down into the hole, D0g reveals for you.

[Outside the Citadel] Carefully climb down the cliff on the left, kill a headcrab in the dark (it guards a medkit) and drop down onto the upper pipe. Wait for the machinery in front of you to come up, hop onto it and then quickly to the right. Turn left, move on, drop down a bit, enter the big hall on the right, follow the rail beneath the ceiling and drop down again, this time to the left. Drop down to a small ledge in the hall where the human capsules come through a laser beam. Carefully advance to enter one of those capsules yourself. Press E at the
