Roswell Conspiracies: Aliens, Myths & Legends is a game based on the animated TV series of the same name. The player takes the role of Nick Logan who has the unique ability to see through alien disguises and accompanies him during his work: catching aliens to save the world. The story follows Logan's missions as he battles various creatures, including werewolves and vampires.
The gameplay involves walking through 15 levels with a fixed camera perspective and shooting everything in sight. Logan uses one of many weapons to do so, all of which have unlimited ammo but require energy regeneration during periods of fire. However, the player doesn't kill enemies for good; instead, they must catch them using an alien trap by pressing a single button.
The game also features puzzles, boss battles, and mini-games, including quick time events that require precise timing to disable bombs or open locks. The levels are divided into five areas: London, Ireland, San Francisco, a Maya temple, and Roswell.
