Overview
Wetlands is a video game created by Hypnotix and published by New World Computing in 1995 for DOS.
Gameplay
The game is a rail shooter with 20 levels. The player can move their view left and right slightly to better shoot at enemies. Level 6, in which the player controls a gun turret, is the only time in the game where the player can move their view up and down as well.
On some occasions, the player can take different routes. On such levels, the player must shoot a minimum number of specified targets before the level ends. Failure to do so results in the player character being automatically killed.
During level 9, the game briefly becomes a kind of shoot 'em up with players controlling a small, robotic drone to disable the security system of an oxygen facility.
