Popular games built on game engine Wolfenstein 3D

Wolfenstein 3D is a first-person shooter presented with rudimentary 3D graphics and a follow-up to the top-down infiltration game Castle Wolfenstein. The game is broken up into levels, each of which is a flat plane divided into areas and rooms by a grid-based pattern of walls and doors, all of equal height. Each level is themed after Nazi bunkers and buildings. To finish a level, the player must traverse through the area to reach an elevator. Levels are grouped together into named episodes, with the final level focusing on a boss fight with a particularly difficult enemy. While traversing the levels, the player must fight Nazi guards and soldiers, dogs, and other enemies while managing supplies of ammunition and health. While later releases of the game included the Nocturnal Missions expansion, this initial release did not.

You're pitted against Dr. Pyrus Goldfire. He's found a way to replicate pure gold, which he's using to fund his maniacal plan. Goldfire has built six highly-secure, futuristic locations where his creations are being hatched. It's up to you to penetrate his security and stop him at all costs.

It's the 22nd century: Galactic travel is commonplace, peace is at hand, and the future looks bright - until Goldfire's plan to unleash an army of military mutants shocks the galaxy. Dr. Goldfire, a brilliant bio-scientist whose morbid research led to incredible genetic improvements in humanoids and aliens, has gone power crazy. And only the galaxy's best agent, Blake Stone, has a chance to infiltrate Goldfire's secret fortress on a remote planet, and end the evil before it's too late. Up against absurd odds, and the most hideous genetic creatures and armed personnel ever amassed, it's up to you to help Blake in his most dangerous mission ever, classified: Planet Strike!

Super 3D Noah's Ark is an unlicensed Christian-themed video game for the Super Nintendo Entertainment System and DOS. It was released by the biblical video game producer Wisdom Tree in 1994, and was the only commercially released SNES game in the U.S. that was not officially sanctioned by Nintendo. In order to bypass the Super Nintendo's lockout chip, Wisdom Tree devised a pass-through system similar to the Game Genie, where the player had to insert an officially licensed SNES game into the cartridge slot on top of the Super 3D Noah's Ark cartridge. Despite its name, it is unrelated to Konami's official Noah's Ark game for the Nintendo Entertainment System. In January 2014, the game was re-released for the SNES, initially available only by private email orders, but later through Piko Interactive's website. The game was also updated for the 20th Anniversary Edition and released at itch.io on May 26, 2014 for Windows, Mac OS X, and Linux. The game plays similarly to Wolfenstein 3D, but the graphics were changed to reflect a non-violent theme. Instead of killing Nazi soldiers in a castle, the player takes the part of Noah, wandering the Ark, using a slingshot to shoot sleep-inducing food at angry attacking animals, mostly goats, in order to render them unconscious. The animals behave differently: goats, the most common enemy, will only kick Noah, while the other animals such as sheep, ostriches, antelopes and oxen will shoot spittle at him from a distance. Goats are also unable to open doors, which the other animals can do. The gameplay is aimed at younger children. Noah's Ark includes secret passages, food, weapons and extra lives. There are secret levels, and shortcut levels as well. The player eventually comes across larger and more powerful slingshots, and flings coconuts and watermelon at the larger boss-like animals, such as Ernie the Elephant and Carl the Camel.

In the year 2012, Foreign Terrorists led by the infamous Victor Baloch have taken control of the Twin "U.N towers" in the United States of America, capturing the leaders of the world who were holding a summit at the time. As a member of the Governments "Elite Force", trained to take out terrorists when the talking stops, you must enter one of the towers through its maintenance area, which can be accessed through the sewers. OBC has 40 levels with the first 5 taking place in the sewers where the player, strangely, fights off giant rats and mutants the manual calls Sludge Minions before they enter the first tower to take on the terrorists. The weapons available to the player include a shotgun with infinite ammo, an Uzi, Galil, Flame Thrower and Grenade Launcher (though it functions like a Rocket Launcher). The aim of each level in OBC is to kill a certain number of terrorists on a map before using one of several elevators or stairs to go up to the next floor. OBC pioneered many features including controllable allies (the other members of your squad that join you once you enter the tower). You can order them to follow you or to roam the floor killing all they find. The player can also freely jump between their bodies in the games take on a lives system; as long as the team member they are in isn't killed there is no limit on this. OBC also features a near fully destructible environment; the Flame Thrower can set bad guys, scenery and the level itself on fire, which could make movement extremely hazardous for the player, especially as the fire randomly spreads. The Grenade launcher meanwhile can destroy any wall (with some hard coded exceptions). Like Blake Stone OBC also features textured floors and ceilings. Though unlike Blake, OBC could have several different floor textures on the same map. However OBC's floor/ceiling graphics were partially parallax meaning they appeared to "warp" as the player moves around.

The year is 2012. A team of U.S. scientists returns from Mars with a small, metallic object - the first hard proof that life exist beyond our planet. Rushed to a top secret underground facility, through a maze-like series of hallways and test chambers, the object is secured in the lowest level laboratory - at the end of Corridor 7. Subjected to gamma radiation, the sphere explodes - transformed into a radiating gateway, linking our world with another. An army of creatures emerges from the pulsating vortex. The Alien Invasion has begun. You are Special Forces Agent, sent to eliminate all invaders, floor by floor - by whatever means possible. Wage a ferocious battle through the overrun military base and reach your destination. Down Corridor 7 looms the fate of the entire human race.
