4) Have at Least 20 Different Combat and Death Animations

Another element of the game that can make the experience seem shallow is the repetitive nature of combat and death animations that can play while you're on a mission. Right now, the amount of animations that can play in battle is pretty limited. There should be 20 different combat and death animations at the very least.

We don't want to see soldiers attack or enemies die in all the same ways every single time. Variety combat scenes is a vital ingredient - a necessity - for immersion. Better detail and more variety in character kill, death, attack, cover and dodge animations would truly make the battlefields of XCOM feel more alive. They should have unique voice effects for each animation.

 
Fight and die.
