Description (by MrFlibble)

A hostile alien force known as the TimeStrikers is staging an invasion of Earth. These creatures use their ability to travel through time to invade and conquer different time periods of mankind's history. As the TimeStrikers attempt to teleport into the late 20 century, a lone special forces operative is sent to stop them. If need be, he should travel through the "time channels" left by the aliens to find a way back to their homeworld and put an end to this threat once and for all.

CHASM - The Rift is a first-person shooter that is quite similar in style to Quake. However, it is more story-driven. Each level starts with a mission briefing, and specific objectives may need to be completed in order to progress through the game. There are four episodes in the game which take place in different time periods: the present day, antiquity (most prominently Ancient Egypt), medieval Europe and finally, the alien dimension. Each episode ends with a boss battle.
