This game was originally called Halloween Harry, presumably because everyone on Earth has been turned into a zombie. Version 1.0 was an incomplete version that only appeared in a UK Magazine. Following version 1.2 version, the game was renamed Alien Carnage and the version number returned to 1.0. The only other difference is that Mission 3 became Mission 1, and vice versa. Despite this change, it remained legal to distribute the shareware version of Halloween Harry, so you could try out Mission 1 and 3 before buying the game! You play Harry, and your goal is to defeat the aliens who are turning everyone into zombies, killing the zombies that get in your way. You get a number of weapons and a jetpack to fly around levels. Gameplay looks and feels a lot like Hocus Pocus. The graphics and animation are good (even sexy in places), and most of the soundtrack is awesome. Apogee stopped selling the game on 21 April 2000, and released a patched version of the registered game when the game was declared freeware. The patched version fixes three problems that users were experiencing on modern computers: the first was a Run Time Error 200 problem, and the other two problems were related to temporary file usage in regards to screen distortion and a missing save game problem. There are 4 episodes in this game, with only the first episode playable in the shareware version.

Mission 1 - Sewers
Mission 2 - Factory
Mission 3 - Office Block
Mission 4 - Alien Ship

Cheat Codes

Customer Cheat

Pressing [B] [I] [G] all at the same time will give you full health and jetpack power. Debug Mode

The following debug keys work for version 1.1 of Halloween Harry only:

[Ctrl] [R] [E] [N] - Gives you all weapons, and activates god mode for several seconds.
[alt] [L] - Level warp. Type the number of the episode (1-4), followed by the number of the level (1-5). Illegal input will dump you to DOS. This can not be used in the shareware version to access levels in the registered version.
[alt] [=] - Change location within a level. Type coordinates after this code; illegal input will probably crash the game.

Tech Parameter

Pressing these four keys at the same time will show you the coordinates you are at on the level. This serves no real function on its own, but it is used by Apogee's Game Hint Line sometimes to locate a player in a level. The keys are [ctrl] [alt] [rshift] [F12]

Misc Command Line Parameter

"skip" will start the game directly from the main menu.
