Twilight_l - Capture the Flag variant.

By Quartz

Objective: Steal the key from the enemy generator room.
Take it to the enemy gas chamber, and touch the 
control panel to release the gas.

Scoring:    
2 points for moving the key outside the generator room.
3 points for moving the key to the yard.
10 points for each gas release.
Notes:
 Only the enemy base is affected by the
gas. Inside the enemy base the respawns and the gas 
chamber offer protection from the gas.
A Gas Mask can be used by both teams, and
be picked up and dropped at anytime.
The canyon grate can be opened by a spy and 
closed by an engineer, by touching the switch
beside the grate. After it has been
opened/closed, there is a delay before 
it can be moved again.
