A left 4 dead 2 map called ‘Metro’ set at a subway station. Created for a game mode called survival where up to 4 players must co-operate to survive hordes of zombies for as long as they can. The idea that I had in mind when I started working on the map was that I wanted to make a small subway station with 2 platforms and with zombies flooding the tunnels. I wanted the players to feel overrun and never really safe.
I started by blocking out just the train platforms and the room connecting them. But after walking around in it and testing it I quickly noticed that size of the map was too small and not that varying, so I decided to add an upper floor which would be the entrance hall.
I wanted the basic layout of the map to be very simple and symmetrical, and then work with props and decals to differentiate the different sides. So the players would have a general idea of the layout even though they might not have seen the whole map yet.
I wanted the players to keep moving at all time and rotate through the map and the different safe spots. As they start on the lower level, which has a lot of gear available, players often make their first stand there as well. To force the players to retreat to the upper level I’ve scripted some extra zombie waves that come from all tunnels after a few minutes.
At the upper level there can be some safety found at the reception where they also find the only source of ammo without going downstairs but the main defensive point is behind the diners counter. To prevent too much camping here I added a breakable segment of the wall, which a tank can destroy to open up a passage for the zombies.
When the players walk in the middle of the room there is often the threat of a smoker on the roof pulling them up through the skylight, this is also common in the hallways.
The players spawn on one of the train platforms and find weapons and ammo in or near the middle room between the platforms. However since the room is so small and has doorways leading straight through it, it’s very hard to defend and therefore used as a shortcut between the platforms.
