While certainly not the most advanced engine, Chasm still has what it needs to be a great shooter.
CHasm: The Rift originally came packaged with an IPX and Serial connection online modes, which were not extremely popular. A later Addon however strengthened the multiplayer option. While the players could choose single player maps to deathmatch on, It was commonly found to be troubling in the matter that all locked doors remained locked, and that someone would need to take time to open everything up. However, there were also six special DM maps, or Deathmatch Arena maps, which had varying styles to them, such as a Tech base, Egyptian Throne Room, or even a medeival castle. However, none of these arenas were spectacular in anyway. Nonetheless, Multiplayer on these maps, especially in large groups, could still prove to be rather fun.
Chasm: The Rift was sold with a Level Editor on board the CD-ROM. However, it has been noted however that the Editor is difficult to use, and that options are very limited in the creation of the maps.
While being fun, the game can sometimes be frustrating. However, the game should provide you with a few hours of entertainment every now and then, and the boss battles should make scratch your heads in thinking, "How the hell do I kill that?". However, the game is extremely limited in what it can do with its rather poor engine.
