ExZeus The Complete Collection‘s greatest sin is just how threadbare it is. There’s nothing to unlock other than a few achievements, and no modifiers to mix things up once players have finished both games. With this kind of retro arcade collection one would generally expect to see things like a written history of the franchise, concept art galleries, and a set of challenges or achievements designed to get the player to go back to the game over and over, trying out different strategies and tactics, encouraging players to see everything the game has to offer. ExZeus, on the other hand, just tosses the games out there for anyone for anyone who enjoys the genre to check out. While there are some thrills on offer for fans of Space Harrier or Panzer Dragoon-style games, there’s literally nothing else here for anyone who isn’t passionate about that specific subgenre.
