A gun that should enforce human teamwork. Should be only given to admins and trusted players. It can have a lot of modes of fire, but I have only thought of three yet:
Rush: The affected human gains 1 credit for each point of damage dealt to alien structures.
Don't feed: The affected human loses 200 credits for each evo he gives to aliens.
Defend: The affected human loses 2 credits for each point of damage done to human structures but gets double award for shooting aliens who have recently damaged human structures.
The reward should be able to exceed the 2000 credit limit.
