This is really annoying. Upon their death, the otherworldly creatures leave behind little doohickeys called data chips. You use these stupid data chips to purchase weapon and item upgrades. This would be a cool feature if it were needed, but you can go through the entire game with a first level weapon and still kick much ass. The Enforcer is just to damn powerful.
Every weapon kills aliens with incredible ease.
And since there is no AI to worry about, all you need are a few evasive maneuvers while mashing that left mouse button and it's victory lane. Speaking of simple I don't mind if developers use another game's engine. In fact, I prefer it. But if it's not done right, you disgrace the borrowed engine, its designers, yourself, your family and the Shaolin temple . Enforcer has got to be the worst use of the Unreal engine that I have ever seen.
