Mortyr

Mortyr 2093-1944 is a Polish first person shooter game created by Mirage, released in 1999.

Set in Alternate History, the game begins in 2093, nearly one and a half century after an unexpected Nazi victory in 1945. The Nazis won the War in the course of a winter offensive that swept Europe, leaving four fifths of its territory under Reich control, and later the destruction of Moscow and occupation of Washington, DC. Such a victory was brought upon, it is said, by a Wunderwuffe of mysterious power.

However, as usual, the Nazi victory did not make the world a better place. No sir, by 2093, the totalitarian worldwide Reich is wrought by weather storms and seems to be nearing closer and closer to Armageddon. A political dissident, General Jurgen Mortyr, sends his son, Sebastian, back in time to discover what led to the Nazi victory - and stop it from happening, to prevent Armageddon.

The game itself is a fairly rudimentary shooter with so-so graphics. It's divided into two distinct parts: one set in World War II (passable) and one in 2093 (ridiculous). Panned globally, it was suprisingly well received in Poland itself, marketed as a global hit. May result in a So Bad,It'sGood reaction in some.

Tropes used in Mortyr include:

Artificial Stupidity: Nazi soldiers in the game are pretty much mindless (though some can do stuff like maneuver and roll, though it's far too uncommon).
Awesome but Impractical: The MG-42 you carry? Well, you've got about enough ammo for three seconds of sustained fire. Each having the same power as a Mauser round (justified, since it's the same bullet). So much for More Dakka.
Boring but Practical: The MP-40 and the laser gun are two basic guns in the game that will pretty much serve you up until the endgame.
Bottomless Magazines: Ammunition for every weapon is stacked into one, continuous bullet feed. Even for the Mauser.
Excuse Plot: There isn't any actual plot in the game: just a series of tubes, err, rooms where you shoot Nazis. Notes are scattered around, but if you didn't Read The Manual and/or That Other Wiki, good luck trying to understand why you're shooting Nazis. Not that you need a why, mind you.
Hyperspace Arsenal: Luger P-08, MP-40, Mauser Kar98k, MG-42, Panzerfausts, grenades... Did I miss anything?
Nazis With Gnarly Weapons: Well, 1944 Nazis at least.
