Chasm: The Rift (also known as Chasm: The Shadow Zone) is a first-person shooter video game developed by Action Forms and published in 1997 by GT Interactive Software, WizardWorks, and Megamedia Corp. Action Forms would later develop the Carnivores series. The game was meant to compete with Quake a year earlier, since GT Interactive lost publishing rights to Activision when id Software signed with the latter.

The player takes on the role of an unnamed Marine whose mission is to stop the so-called "Timestrikers", mutant beings invading different time epochs, from taking over Earth. On this mission, he visits various locations ranging from military bases in the present to Pharaonic tombs in ancient Egypt. All of the levels involve dark corridors, often like that of catacombs and crypts.

One of the most notable features of the game was the ability to remove limbs from enemies.

A underrated fps classic that is screaming out for a decent remaster. For its time Chasm had some impressive features especially for such a small budget game.

It has pretty great visuals. The engine uses fully 3d models while the environments are 2.5d. So this meant the game could run pretty good on less powerful pcs back in the day when compared to Quake and then its sequel the even more advanced Quake 2.
It also meant the 3d models could be pretty detailed the enemies look really good and are well animated. You can even shoot off enemies body parts. Its a very simple game and has its own unique charm and is a good example of classic 90s fps games.

It was developed by the same team who would create the more popular Carnivores series. Chasm and Carnivores even share some assets.

If anyone would create a mod that mixes Carnivores with Chasm that would be pretty freaking great. Chasm and Carnivores sharing the same universe could be really interesting. Chasm is not a masterpiece but it is a lost gem and really deserves more attention.

Bought a Doom 1 game,and Chasm was the other CD in the double case. For it's time,Chasm was a good atmospheric game to play.Although my experience in playing vid games was relatively new at that time.

Whoever thought that was an acceptable game summary needs to be burned alive.

Unfortunately not. There is a map editor (which ***** up the files and requires hex editing as well as various other problems) included in some versions of the game.

The .CAR format is somewhat similar to the one used in the Carnivores series though which has been extensively modified by me and others and has two separate editors created by members of the community. If somebody wants to take the time to look at and document the Chasm file formats, it probably wouldn't be too much work to incorporate into said editors.
