Thexder is a compelling retro action platformer, originally launched in 1985 by Game Arts. This game takes you on an exhilarating journey as you navigate through numerous challenging levels, combating an array of enemies that progressively become more difficult. As a player, you are in control of a Battletech-style mech that has the unique ability to transform into a jet at your command. Your primary weapon auto-aims, providing you with strategic advantages, but be cautious of your energy consumption as it needs to recharge after each use. Test your skills with the built-in shield mechanism, but remember it also consumes your life energy. Thexder gained significant popularity in Japan and internationally, with over a million copies sold worldwide, making it Game Arts' most successful title of 1987. It's a game that undoubtedly left a significant mark in the run-and-gun shooter game genre, paving the way for popular titles like Contra and Metal Slug.
