I got struck in solving the puzzle in a room where we have to open the door to collect rocket launcher and its ammo and also there is a health meter at the top and there is no way to go to the top. can anyone please help me in solving this one. Its really banging my head.
my sisters just sussed this one out! pull down the metal flap thing in the middle of the room. stand on it and place ( not throw) a grenade on the ground where the blast marks are. when it goes off you will be catapulted up!
It's actually safer to stand in front of it's edge, toss the nade under, then hop on it. Throwing the nade from on top of it can damage you as they don't roll down easily that way.
