This pack doesn't include Commander Keen 6 and Keen dreams is missing. Some people have been disappointed because that game wasn't included, so be aware! Don't get this pack if you’re planning on playing Keen 6 and Keen dreams.

This review is mainly pointed towards Commander Keen 5: The Armageddon Machine, because I played the living ♥♥♥♥ out of it when I was a kid. I remember getting this game from my uncle on a floppy disk, I took the disk home and installed it, with difficulty, back then I didn't knew much about computers. I finally managed to install it and then I started playing, and I was blown away because the game was so ♥♥♥♥ing awesome. I loved messing around in the levels and exploring them, I died a lot because this was the first real game I played on PC, then I discovered this strange option called 'save' and it remembered where I was! English isn't my native language so I had trouble understanding some parts of the game. I still remember the big red guy with the automatic rifle who instantly killed you when you were in his sights, when I first encountered him I literally jumped out of my chair, I had never seen something to frightening.

And effectually I was there, the final level, I remember every second of that remarkable level and when I finished the level and I had beaten Commander Keen 5: The Armageddon Machine, I felt great I had conquered this beast of a game. After beating the game I spent hours upon hours replaying the levels and playing pong. Later I found out that if you pressed F1 (or some other button I don't really remember), the game would load a page with the LORE of Commander Keen 5: The Armageddon Machine, the ♥♥♥♥ing Lore of Commander Keen 5: The Armageddon Machine, holy ♥♥♥♥. And when I found the 'lore' I looked at the pictures of all the enemies I had encountered and I even saw pictures of enemies I didn't encounter, because you could only encounter those on hard mode. (I just looked at the pictures and because at the time I didn't speak a word English.)

Years later I found out Commander Keen was available on steam and I had some money on my steam wallet and I was like: ♥♥♥♥ it I'm buying Commander Keen. And I was able to play my childhood love yet again.

Well enough of MY experiences with the game, lets actually talk about the game. It's a miracle if you actually read my story and made it so far!

Commander keen is simple platformer, it's about a guy, Keen. From my current understanding he is just a dude who travels to random planets and shoots aliens with his little laser gun, he also has a pogo stick which makes him jump higher. This pack included Keen 1,2,3,4 and 5. The first ones look really old, but the fourth and the fifth looked a lot cleaner and a lot newer. All of the games play pretty similarly and have the game character and weapons. But I didn’t really finish any other Keen game except Keen 5, so I might be wrong because some things are different later in game. But in Commander Keen 5 you have to collect four diamonds to open doors to continue within the level, then you have to find a key that opens the door to the end of the level, later you have to destroy something what looks like the power source for the space ship you are stranded on. In the game you will encounter various enemies, some are robots some are 'energy enemies', the robots can be killed the 'energy enemies' can only be stunned or can't get hit at all. You have one life, so if you get hit once you are done for, yet you can save everywhere you want, so that isn't a big problem or a hard part about this game. All in all it’s just an old school platformer, that is as unforgiving as any other old game and needless to say the game is also very fun!

After playing this game again after so many years, it made me realize that Commander Keen 4 is way superior to Commander Keen 5, because the fourth installment had way more variety. And when I look back at the levels of Commander Keen 5 I realized that they game wasn't really that special. It was just the fact that it was the first game I ever played and finished, what made it so great. The nostalgia made me love this game.

Nostalgia is a ♥♥♥♥♥.

Thanks for taking the time to read my game review of Commander Keen, one of my favorite games if not my favorite game of all time!

A simple platformer with excellent design, Commander Keen, developed by id sofware, was revolutionary in it's day and was the first action sidescroller on PC. It features large, non-linear levels in which you need to navigate to the exit, which is most likely blocked off by a door requiring a key which is hidden on the map somewhere. The levels get more complex and the design gets crazier as the game progresses along with gaining difficulty as you'd expect. Overall this is a solid platformer, even by todays standards, it offers great gameplay, great design and a lot of replay value, this comes with 5 Commander Keen games, so instead of paying 15$ for some indie platformer that tries to mimmick games of Commander Keen's era, get the real McCoy!

Works with controller.

Commander Keen in Invasion of the Vorticons was the first side-scroller on PC. This is a piece of video game history. This is a must own for anyone interested in the history of video games. This was also the first game created by id Software, the creators of the First-Person Shooter. So much History!
(But be warned, this is not all of the Commander Keen games/episodes. It is missing Commander Keen in Aliens Ate My Baby Sitter! and Commander Keen: Keen Dreams. This IS NOT a "Complete Pack"!)

PC kids of the 90's didn't have Mario or Sonic, they had Keen. Football helmet, pogo stick, and attitude.
Commander keen is the story of Billy Blaze, a kid who manages to figure out space travel and therefore take on an alternate identity keen. He starts off crashing on mars, and goes through many platforming adventures there looking for parts to rebuild his spaceship. The levels are full of obstacles and collectibles, as well as very exotic alien races bent on touching and therefore killing you.
The game is slower paced than other console platformers, but it charges you with finding keys to progress through its levels, and navigate complex terrain via pogo stick.
It is a fun, but quite old series of games. For people who like old style platformers with some imagination. Its a good time waster, and doesn't require the same raw platforming skills of a mario game.
