This is a totally unique map that SUPPORTS ANY GAMETYPE.

Fortress 2 is an asymetrical slayer/infection (recomended) map that is ideal for large parties. It consists of 2 asymetrical forts that have a balence mixture of wide open spaces and tight combat places. Fortress#2 (on the screenshot below) can be explored by a warthog on both floors.

The map Fortress 2 consists of every type of grenade EXCEPT spike.

2 sniper rifles
2 BR
1 warthog
2 carbines
1 grav lift
1 bubble shield
1 radar jammer
1 warthog

Placed uneavenly (but stretegicaly) somewhre on the map.

SLAYER

On slayer this map is very origanal. Most maps have 2 pre-set bases but not Fortress 2.
In Fortress 2, both teams (if not FFA) respawn on the 2 sides of Fortress 2. After both teams battle the winning team can choose between the large 2nd floor and cover of Fortress #2 and the 3 story rallying Fortress #1 which overlooks Fortress#2.

INFECTION

This is what Fortress 2 is made for! Humans start in middle of the map where they have 20 seconds to hide in the one of the fortresses before the zombie attackers are unleashed! The maps are set so the game won't end to quickly but there are no dead ends so humans don't camp.

The zombies respawn in double boxs and are trapped until man cannons respawn later in the game.

OTHER GAMETYPES

As said before Fortress 2 supports every gametype. With gametypes such as CTF and Assault, the score places are on both sides of Fortress#2 and Fortress#1 can be used as a rallying point.
