Other engine features Raven Shield include the “rag-doll” physics that were put into Unreal Tournament 2003. Shoot an enemy in the head and he won’t simply slide into the adjacent wall; he rolls down onto the ground in a more realistic fashion. AI is also very good this time round with enemies noticing shot teammates, taking covering and flanking position and generally acting like real human enemies. Your own AI teammates can also hold their own as well even if you don’t wish to control them.
