Half-Life 2 Hints
Gas Canister Tip
1 of 3: There are four explosive gas canisters up on your floor of the building.
2 of 3: You could try throwing them down at the zombie and headcrabs below, but it's actually easier to gently drop them down and then detonate them with several pistol shots.
3 of 3: Any canisters you don't use should be dropped down to the floor below so you can use them against the zombies in the area ahead. (Not necessary, but possibly useful.)
