DOOM 3 is a first-person horror video game released in 2004. It is the third installment in the DOOM series of games. The game’s storyline is not a continuation of the two previous DOOM games. The game is set in Mars in the year 2145 and the objective of players is to defeat enemies and successfully pass levels. Players have ten weapons to use, such as guns, explosives, plasma weaponry, and many more. There are different types of enemies in the game including zombies, monsters, and demons. Friendly NPCs (Non-player Characters) are also spread throughout the game. They can provide information, objectives, and give players some useful items. Players take the role of a space marine corporal who has been sent to a base in Mars. Game objectives are given out by Master Sergeant Thomas Kelly.

DOOM 3 can also be played in multiplayer mode that consists of four game modes. All the game modes are based on a deathmatch game system wherein players need to eliminate other players in order to win. Community members have also created a game modification that allows up to 16 players to play simultaneously in multiplayer mode.

Here are other features of the application:
• Complex animations
