Chasm: The Rift is a first-person shooter for the PC developed by Action Forms that was published in 1997 by WizardWorks Software, GT Interactive Software and MegaMedia Corp. In the game, you take control of an unnamed Marine whose mission is to stop the Time Strikers, mutant beings invading from different time epochs, from taking over the earth. On this quest to stop the evil forces, you visit places ranging from military bases in the present to tombs in ancient Egypt. One of the notable features of the game is the ability to remove limbs from your enemies. The bosses in the game have to be brought down by special tactics instead of raw firepower. There is an official addon to the game that adds three new levels along with new monsters and is available as a free download from the developer's website. Though the retail CD contains a level editor, no user-created levels are known to have been published on the internet, making it hard to find new content for the game. Chasm can also be edited using the Doom WAD editor XWE.
The game received mixed reviews at the time of release. While many reviews gave points to the game for being a simple and fun shoot-em-up that, because it only supported software rendering, didn't need the biggest, baddest PC to run it, it got a lot of flak for being too simple and not being as good looking as the game it was trying to be, Quake. It also received flak for not being about to look up and down, like in Quake, so it feels like a chore and that it's multi-player was barely worth it, considering that Quake II was on the horizon. However, the game has lasted throughout the years and has gained a cult following.
