Evolution Points

Evolution Points are the Alien counter part of the Humans Credits. They are commonly reffered to as Evos. Evolution Points are awarded to a player when a human they have done damage to dies, the amount of Evolution Points received is proportional to the damage dealt. Evolution Points are used to evolve into other classes. An Alien player can possess a maximum of 9 Evolution Points at a time.

If you are playing on a server that does have the Donate or the Share feature, you should give Evos to your teammates if you have too many. Otherwise, valuable "energy" that your team could use is lost, because every Evo that you earn beyond the 9 Evos you might already have is just lost forever.
