1f:T63d,

Based on: Pit

Gametype: Last Defense (Infection; Click to Download)

Description: The base is inside and underneath the OPS Center (the sword building). The base starts off with nothing blocking the entrances except a few roadblocks. The base gradually gets stronger as the game goes on, though. So after one minute the entrances are partially blocked off (and a few weapons spawn) and at the end, after three minutes, the entrances are almost entirely blocked off. The way the map is set up allows the zombie to alter the base if they change the geometry before the next item spawns (for example if they move the barrels in the inside base before the generator spawns on top, the generator will fall). Everyone I played with loved this map, so I'm sure everyone here will too. ;)

Screenshots:

These are all after the three minutes is up, when the base is at its strongest.
