Bij Gamespy hebben ze de demo van KISS: Psycho Circus exclusief gekregen van Third Law Interactive, de makers van dit spel. Het spel maakt gebruik van de nieuwe LithTech 1.5 engine.

Hieronder staat wat we allemaal in de demo terug kunnen vinden.

Included in this demo are five levels: two from the Water Realm, one from the Earth Realm, one from the Air Realm and one from the Fire Realm. The full game includes 47 maps. The demo is single-player only. Be sure to play through all five levels -- the first two levels are deceptively simple, aimed at getting new players involved in the gameplay. The other realms begin unleashing the hurt without mercy...De demo is bij Fileplanet te downloaden en ca. 73 Mb groot.
