How it plays
The game is viewed from the side across large, scrolling stages. Harry must move through urban environments, defeat aliens, rescue endangered civilians, collect weapons and power-ups, and reach the end of each level. Platforms, ladders, hazards, locked areas, and hidden routes make exploration part of the challenge.
Players can run, jump, climb, and fire in multiple directions. Ammunition and weapon pickups encourage switching tactics, while health and other bonuses help sustain a run. Levels culminate in dangerous encounters, and the campaign becomes more demanding through tougher enemies and more complicated stage layouts.
Plan your run
Keep moving while firing; many enemies are easier to handle when approached from a distance. Search side rooms and upper platforms for weapon and health pickups before advancing.
Use ladders and vertical routes carefully, and avoid rushing into unfamiliar screens. Save stronger weapons for dense enemy groups or dangerous encounters rather than spending all ammunition on isolated targets.

Halloween Harry is a side-scrolling action platformer developed by Moonlight Software and published by Apogee Software for DOS in 1993. Players control Harry, a heavily armed hero fighting an alien invasion in a city filled with burning buildings, hostile creatures, and civilians in danger. The game combines traditional platforming with run-and-gun combat. Its shareware-era presentation emphasized fast movement, frequent shooting, and colorful science-fiction horror imagery rather than complex storytelling. Halloween Harry was well regarded among DOS players for its accessible controls, varied weapons, and energetic level design. It was later distributed under the title Alien Carnage in some releases and regions.
