After the first five Commander Keen games, Apogee stopped making them. Soon after, FormGen came around and made Commander Keen 6, which is the first Commander Keen game that wasn’t made by Apogee, and the obvious reason why it’s abandoned. Since Apogee is very touchy about their games, this will unfortunately be the only Commander Keen game you'll get for free for a long time. But in the meantime you can rejoice, because you have Commander Keen 6: Aliens Ate My Baby Sitter!
The game was made in 1991, the same year as the fifth Keen game was made. The game uses the same graphics engine as parts 4 and 5 and is just as enjoyable. You are Billy Blaze, a young genius and inventor. When the mean, green Bloogs from the putrid planet Fribbulus Xax came to Earth, they kidnapped your babysitter, Molly. Now you are the one to go to Fribbulous Xax and save her (how many kids are there that would risk their lives just to save a babysitter!?). You change to your alter-ego, Commander Keen, and head to the planet. The only weapons that you have are a neutral stunner and a pogo stick! Your mission won't be easy, as there are many evil aliens that will try to hurt you. However, there are some good aliens that won't hurt you; they just push you. But time is precious, so don’t waste it on playing with aliens! Run and save the queen, er, I mean the babysitter. Explore the planet’s surface and search the guard posts, research labs, and space stations. While you explore the surface of the planet, you may also find some paths that are blocked. In order to unblock these paths, you have to complete one “small” arcade sequence. You only have a set amount of time and lives, so be fast and careful.
The brilliant EGA graphics make this game even more enjoyable. I don’t have any complaints about the sound, either. It fits the game perfectly. The only annoying sound is the one when you get killed, but that’s only because you know what just happened.
The game is easily played by using the arrow keys for moving, Ctrl for jumping, Alt for activating the pogo stick, and the spacebar for firing. One more thing that I like a lot is that Keen can hang down from ledges and climb up. I really liked this game. I would suggest it to everyone, no matter the age.
As far as my rating, I give this game a straight 5.
