10 Fun Free and Open Source First Person Shooter Games

First-Person Shooter GamesThis is a computer game genre focused on guns and other weapon-based fighting using a first-person perspective. They are a type of three-dimensional shooter game. Pick up your weapon, enter the battle arena, and take on your enemy in these fast and furious games.

It’s sometimes claimed that the concept of a first-person shooter originated with the release of Doom, almost 30 years ago. While Doom was definitely not the first in this genre, although it was an important game in promoting the genre. One of the earliest FPS games was Spasim (“Space Simulation”) released in March 1974. The game included wireframe 3D graphics, local multiplayer, the first-person perspective, and ships and weapons based on Star Trek. The game was played on the PLATO computer system and was heavily influenced by another PLATO space multiplayer game Empire.

All of the games featured below are highly addictive, immersive, fascinating, and hugely satisfying. Attractive graphics are an important element to any shooting game. But these games also have great gameplay coupled with the urge of always having just one more play. And as the source code is freely available, anyone can pick up, modify, and expand upon the games.
