In Commander Combo, the player takes on the role of a commander tasked with defeating the dangerous and brutal smoker Uli Trimpe, who has occupied five colonies on the planet Boot II. With 50 challenging platform levels full of traps and enemies, players must guide their character through various obstacles to emerge victorious.

While the game's premise may sound a bit outlandish, the gameplay is anything but. In order to free the colonies, you'll need to beat 50 platform screens, each with its own set of traps and enemies. To progress to the next level, you'll need to collect a ruby - but be warned, some levels may require you to find other items first.
In addition to the regular enemies, you'll also have to fight off bosses like vampires and wannabe-archmages. While these may seem intimidating at first, with a bit of knowledge, you can learn to defeat them easily.
One thing to keep in mind is that the game can be quite challenging. Bonus lives won't appear when you need them most, and you'll have to rely on your own skill to progress. But the game is also quite rewarding - each time you beat a level, you'll feel a sense of accomplishment that few other games can match.
Overall, Agent 4X-019 #Y Codename Combo is a great choice for anyone looking for a challenging platformer with a unique storyline. If you're up for the challenge, give it a try - but be prepared to work for your victory!
Version 2.5: Several minor corrections and improvements. The game no longer uses Direct X, so it can now also be played in full-screen mode. An updated runtime library is included.
