Day of Defeat: Source Underground Map

Grenades can ALMOST make it in, perhaps wounding those inside. This map has 7 flags, a sniper tower, a rock maze, and an underground tunnel. There is a secret room, although is may be hard to find unless you are looking for it, and even then, good luck. Arena style map.
This is a map situated underground. It features an un-enterable spawn point due to the landscape, and in the event of someone overcoming this, the enemy will immediately be killed upon entry.
