Even the dumbest farmer from the Lamo galaxy knows that two rifles outshoot one. The Sentry gun is a self-operated device which when unfolded automatically seeks out enemy targets and rains down piles of bullets upon them. Ideal helper for defending the base or for added support during larger attacks. ONLY FOR ZONE CONTROL
Sentries can be useful for atacking and defending, If you are defending It can be placed on a corridor or zone where enemies are coming, and if you are attacking you can place it near the enemies hiding spot, a sentry gun can be destroyed by plasma (but not at the first hit), but an EMP grenade will sure take it out, It dissapears when its owner is killed or when someone does a physical attack to it.
