zombie apocalypse

*you are a survivor in a zombie apocalypse in Ashtown... a small safezone with few supplies and a laboratory... the lab is locked by a keycard reader meaning you need a keycard... there are some locations you can visit but you can always just make up one or something so here are some of them: Ashtown which i mentioned before, East black mesa which is a city that is filled with hordes of zombies and is the most dangerous, West black Mesa which is another safezone, The radio station (it has a secret), the church, the power plant and the mines... the mines are extremely dangerous since you need a gasmask or a hazmat suit to enter because the thing is filled with toxic gas and has some biohazard waste... also there's some radioactive water WHICH YOU SHOULD NOT TOUCH AT ALL COST AND ABSOLUTELY NOT DRINK IT...(btw the gasmask is in the powerplant and the hazmat suit is in the city but you can decide where you can find them as well) there's also some sort of a creature living down there... I'm not recommending going there... also, remember how i told you that the radio station has a secret? well its where the keycard is hidden... you can do absolutely anything I'm not stopping you! also I'm making an SCP-3008 talkie next time so enjoy dudes! just don't mind the voice pls* (Btw this is inspired by an actual Roblox game named Boys girls Vs zombies!)
