Builder

A builder is a player that can construct structures (buildings). For human players, this requires a Construction Kit, for aliens the player has to be a Granger. Any player can be builder (just get a ConstKit / become Granger). There can be any number of builders on a team (but there doesn't have to be a builder at all).

When a match starts, both teams already have a default base, and also some more build points (BPS). The builder(s) use these BPS to extend the base, add more defenses, restructure the base, or even do a whole base move. Human builders also have to repair damaged buildings (alien structures don't need this as they heal automatically).

Human can directly spawn with a Construction Kit or get it at the armoury. This gives the human some flexibility: if their base needs repair or new structures, they can quickly become builder and switch back to fighting afterwards. As the human buildings don't “heal” automatically, this is also required once in a while. If your team does't have a permanent builder who takes care of the base, it's a good idea to get a ConstKit every now and then and make sure that all buildings are ok and that no BPS are wasted.

Alien players can become builders by spawning as Granger. Grangers can evolve to fighting aliens, but non-Grangers cannot evolve to Grangers! This means that when your team has lost all eggs and you have no Granger, you can't build anymore (as opposed to humans, who can still get a ConstKit at armoury).
