Hello! This is a campaign map. It's a short story-driven linear experience about a city 17 citizen (you) who is stuck in a hospital overrun by zombies (more detail in the Storyline section). The map is heavily inspired by the hospital from hl2 ep1.

-Requires Half-Life 2 Episode 1 mounted

-This is a singleplayer map and attemtping to play with other people will have unpredictable results (Prepare for unforeseen consequences).

The events in this map take place before the events of hl2. You play as a patient in one of city 17's hospitals where a shipment of headcrab canisters leaks and an infestation begins. The mayhem eventually causes an explosion when zombies manage to interrupt a surgery and damage the oxygen supply, resulting in an escalation of the crisis. The Combine Overwatch issues a lockdown, and soon after, all patients are designated a bio-hazard and a kill with discretion order goes into effect. Now you must escape the hospital and find a way to leave the lockdown area. With any luck you won't be the only one to make it out.

This map was originally made for hl2 ep1, but I changed it up to work in gmod. The ep1 version features actual autosaves (as opposed to custom checkpoint and respawn logic) and some additional animations for the headcrabs that failed to work in gmod. This version is not currently uploaded anywhere and I should really get on with doing that...


-Special thanks goes to the people in the SDK Discussion page who've helped me figure various problems during the creation of this map.
-Valve, for making this possible

Do not build upon or change and repost this map in any way.

If you plan to decompile this map, I warn you that the map file is really messy as this map was developed during my earlier years of map making. Most things are aligned to grid size 1 or are occasionally clipping through each other, and there's an excessive amount of cuts and other scary things. Presently of course I am capable of structuring my projects like a normal person lol.
