No Exit (video game)

No Exit is a one-player game developed by Coktel Vision and released in 1990 for the Amstrad GX4000.

No Exit is a side-view martial arts Beat'Em Up, similar in style to IK+ AKA International Karate+. Each fight must be won within a time limit. You can specify your character's ability quite precisely, trading off Vivacity against Efficiency and Resistance against Strength. Your character has a special destructive mode, which can be accessed three times. This turns the character into a monster (corresponding to the opponent you are fighting against) and increases the level of damage you can inflict.
