just zombies is too crickets. i like different kinds of enemies and environmental hazards such as anomalies of various kinds and weather "emissions" in the game s.t.a.l.k.e.r.. an emission is a violent, short-duration, weather phenomenon where you must go indoors and wait it out, or its insta-death. anomalies are permanently located in certain places and have different properties. can be electrical, fire, gas, gravity, etc. in these anomaly areas you can hunt for "artifacts", item addons that give/take away attributes. plain old aidz zombies got boring somewhere between dayz and warz.
