Gameplay
There are a fixed amount of players per team; all others spectate. The amount of players varies depending on the map; for example, ATCS might have 5 players, while Karith might have 8. Each team has 1 builder. There are 7 rounds. For the first 2 rounds, the teams are s1, the second 2 s2, and the last 3, s3. The team that wins the most rounds wins.
The round is divided into 5 stages. The first stage is a short break of 30 seconds where the players may discuss strategy.
In the second stage, players may spawn, but may not attack, buy weapons, evolve, or build until all other players have spawned; they may not leave the area of creep/bp during this time. (This could be enforced via solid barrier or instadeath followed by respawn).
For the third stage, players may buy weapons and armour, evolve, or buy feats. The builder may not buy weapons and armour, or evolve. The players may not attack ducring this time, nor may the builder build. The second stage ends after a default of 15 seconds.
In the fourth stage, players may build and attack as normal. Deaths are permanent until the next round. This stage lasts 5 minutes.
In the fifth stage, the medistation and booster are disabled, as well as the effects of creep. Builders may not build but may repair (similar to sd). All players will lose 4% of their maximum health each second. The last surviving team wins that round.
Optional Rule:
The position of builder is assigned randomly each round. The builder get 1 evo/400 credits multiplied by the amount of time they were alive. (For example, joe is builder and is killed at the 4 minute mark. He gets 400*(4/5)=320 credits)
Scoring
Players earn the normal amount of evos/credits per kill.
Players earn 1.5 evos/600 credits for destroying a node. The node will be recreated the next round.
The whole team earns .25 evos/100 credits per member of the opposing team if all of the opposing team's members were killed.
Feats
Feats are special abilities that players retain throughout all 7 rounds. New feats are attained at every stage, and are unique for humans and aliens.

Aliens
Extra HP: 15% more hp. 1 evo
