X-COM: Enforcer

During the First Alien War of 1999, a scientist named Able Standard was tasked with the objective of creating a powerful combat robot. Due to funding problems, the project was officially abandoned; however, Professor Standard secretly continued working on it in a secluded area in the Nevada desert. Eventually, he succeeded in creating the ultimate warrior - the Enforcer.

X-COM: Enforcer is an arcade third-person shooter based on Unreal Tournament technology and set in the universe of X-COM, which previously hosted squad-based strategy games and a space combat simulation. Completely different from its predecessors, this fifth installment offers arcade action spread over thirty levels.

The player controls the Enforcer, sent to combat the alien menace. Professor Standard offers help throughout most of the game. The player can select one weapon at the time and have the Enforcer run and strafe around, while holding the left mouse button to shoot. The stage is usually over after all enemies and transporters have been destroyed. If the player managed to collect the word "bonus", he will advance to a bonus level first.

Every two levels the player is able to access a shop where different upgrades and weapons can be bought. If the player has found a question-mark icon in the previous level, a new weapon or power-up will be unlocked.
