Alien

The aliens are a class-based team working off the idea of evolution points being awarded for staying alive and for killing humans. Aliens may use these evolution points to evolve into a stronger class.

The aliens (at least at the weaker stages) work off of their speed and agility.

Aliens, like humans, begin each game with a default base, but it is normally a good idea to build additional spawns and defenses. Alien buildings are generally weaker than human buildings, but the aliens themselves are generally stronger than humans.

Aliens use evolution points (evos) to evolve to other classes while humans buy/sell their equipment. Aliens can not evolve into lower (weaker) classes. For example, aliens are unable to return to being a builder in order to reinforce the base with new buildings without dying. However, aliens can evolve anywhere on the map, as long as they are on a safe distance from human players and buildings and as long as the Overmind is up.

All aliens have 2 passive abilities:
 * Regeneration - Each and every alien will heal each second as long as it's not being hurt. The amount depends from class to class. They can double their regeneration speed near a Booster or a Tyrant.
 * Radar - Aliens can sense human presence as long as they are within range. This is represented by blue and red dots at the edges of the screen. The blue dots are living humans, while red dots are their buildings. Aliens can only detect the direction of the target and whether they are a player or a buildable. They cannot detect other aliens.
