Originally called Halloween Harry after the protagonist, following v1.2 the game was renamed Alien Carnage and the version number returned to 1.0. The premise is simple: almost everyone on Earth has been turned into a zombie, and Halloween Harry must rescue humans and defeat the zombie overlords. 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. With the name change to Alien Carnage, Mission 3 was swapped with Mission 1. 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! Halloween Harry v1.0 was sold by Manaccom in Australia before Apogee became a publisher. Whether or there was a shareware version is unknown. 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.
