Doom is a true classic game of the DOS era. This game was the second game in the first person shooter genre based off of Castle Wolfenstein.
In doom you battle the minions of hell on the moons of mars due to the Union Aerospace Corporation's (UAC) failed development of teleportation. During the preliminary tests of the teleporter, which takes you through hell to get to your destination, demons manage to escape hell and start wreaking havoc on the Phobos moon military base.
You are the last member of an elite marine strike force stationed on the Phobos moon.
You're thrown into the game with nothing but a pistol and some ammo. However if you’re clever you can get a chainsaw immediately. Throughout the levels you battle standard pistol zombies, shotgun zombies, imps, spectres, demons, hell knights, arachnons, cyber demons, and the evil spider mastermind behind the whole invasion.
The graphics were considered top of the line for their time. However the game was only an imitation of a 3 dimensional world. All the levels are nothing more than a series of 2 dimensional graphic files. Game controls were fairly easy to master since they were nothing more than movement and a fire key. The game did not include mouse support or the standard aiming features of today's first person
shooters. The game had a built in aiming were all you had to do was have your weapon pointed towards the enemy you wanted to kill and weather they were above or below what looked to be your projectile path the game would adjust where the shot actually hit. Basically there was lateral aiming, all vertical was automatic.
As for the arsenal of ass kickers available to you there was the chainsaw, pistol, shotgun, double barrel shotgun, chain gun, rocket launcher, plasma rifle, and the almighty BFG 9000.
While an extremely entertaining game the levels could be very repetitive seeing as how the only object of the game was to kill monsters, collect keys, and find the exit of the level. Even with the excessive repetitiveness of the game I found it to be one of the greatest games ever created for the PC. Later program such as ZDOOM allowed you to use the map packs from the original game inside a new shell that allowed you to have the standard aiming feature better controls as well as the jump feature which allows for better access to many secrets and in some instance completely skipping a level because you had to get to a ledge that was just above ground level but had to teleport from the other side of the level too.
All in all I would highly recommend this game to every first person shooter fan out there.
