About Aliens versus Predator: Extinction

unit limit - pitiful 25 for marines, 45 for xenomorphs and 12 for predators.
objective indicator - not always present, though these usually explicitly tell you to find it.
status effects - some of the upgrades cause these, especially the xenomorph ones. The flamethrower upgrade makes the most sense. The predator bleeder spear makes some sense but is implemented in a very status effect-like manner.

Faction specific tags:
* Marines - healing, repairing, most weapon tags
* Aliens - autoregen (only with few aliens or at specific locations)
* Predators - pole arms, all energy weapons, energy regen
