This is one of of the Most interesting genre ever made, and Altar have proved the ability to make UFO's! People say the game is difficult, but on the second difficulty, when I produced the firs sniper, there were no alien to oppose me! I'd rather prefer if the aliens are more difficult - the experience to be more, but anyway it was amazing. Advanced weapon render the snipers obsolete, so do not train many sniper solgiers. Consider trasining more solgiers of the type Scout-Leader-Techic(machinegun) and Gunman-Trooper-Tecnic(rifles) that was my main power, ofcource always carry one-three snipers. The bugs are not much, I sensed wehen the game crushes and I avoided the events causing them, or always save before You sense the crush.
