X-Men Origins: Wolverine Walkthrough

Go upstairs, and mind the three grenadiers. Bounce them back and when they die, there's some more enemies that spawn. Lunge over. Clear out the enemies, and then go through the door. Right near where the path turns left, there's a body with a Dog Tag.

Up the stairs, things get a little hectic. Keep to the sides and stay covered and take on enemies one at a time. In the next room, kill the two enemies and take the lift to pursue your prey. Head down the halls until you see him running.

Enemies will spawn, including Goliaths, which you need to use charged strong attacks on. When they're dead, go to the end of the hall and pry the door open. In the halls, keep a look out for the Samurai mutagen and then pry open another door move on. There are a couple more Goliaths, which you'll want to lure away from the grenadiers. You're back in the room where you moved the truck. Go through the small door on the bottom floor to find Anna.

It's time to escape through the spillway. Things are pretty easy until they start mixing elites and grenadiers, at which point you'll need to do some trickier countering. After that, the floodgates open and it's time to book. Run until you're in range of the trucks, and then lunge. Hack your way from truck to truck. On the last one you'll have to reflect a grenade and kill your enemy from afar to trigger the level end.
