RESIDENT EVIL 3

Open the spoiler to find where and when this takes place.



You will be in the hospital lobby after the cut-scene, boxes and crates are piled against a door that you have to defend against zombies, preventing them from getting into the room via the door on the other side.

Zombies will start pouring through 3 open windows while your main man will be closing the shutters remotely, in the slowest possible way, leaving you to shoot some zombie brains to thin their numbers.

So, the strategy then. There are two generators by the center and left-hand window (as you are looking at them from the reception desk). Sticking behind the reception desk gives you plenty of time to prioritise your targets. Shooting the generator next to the door you're defending stuns those zombies long enough for you to clear the room of additional zomb's. Unlike all other zed's, once they go down they don't get back up again, so when you've dropped a z, forget him, and move onto the next.

Pick up the detonator early on, it's near the middle window in a crate, along with some ammo. It's handy to have it in you inventory for the final part of this.

When the lights go out, BEWARE, you are about to face a Hunter and he'll be coming out of the door behind the reception desk, so move to any available space either side of the desk. I found you can kill these easily with one grenade on normal difficulty, so it's probably 2 on hard, I'd appreciate anyone being able to confirm. Mine ammo or explosive ammo is just as useful. The room which the hunter came out of if full of flash grenades and frags so fill up on those and head back out before facing more waves of z's and another Hunter.

Eventually, when the shutters are down, you'll be told to set the detonator. There is C4 in the same container you got the detonator from. The main lobby doors will be wide open by now and z's will be pouring in. Set the detonator and you will have 20 seconds to keep the z's from the door. Head behind the reception desk, I actually nipped into the room behind, and focused on the z's attacking the door. Hold out until the timer reaches zero for a cut-scene and the achievement.
