First off, if I am correct the episodes 1-4 are now freeware. Episode 5, however, is not, plus you save the work of installing dosbox yourself (not a big deal, unless you run into trouble with it's textual interface). And a gimmick that practically doubles the value of this buy is a free fan-made mod "Keen 9" (google to find) which requires Keen 5 to play.

My ingame time in this game is, according to steam, low, but that does not tell the whole truth. I have played this game a lot more outside steam.

Commander Keens are 2d platform games from the time 25 years ago. Keen 1 - Keen 3 are on roughly the same game engine, and keen 4 - 6 run on roughly the same redone game engine, which has a much more modern feeling in it. (Keen 6 is not legally available anywhere, it is so-called "abadonware"). Keen 7 is a fan-made mod of keen 4, keen 8 of keen 4 and keen 9 of keen 5.

The first three keens may be just a bit too simple for many a modern gamer to enjoy. But if that bothers you not, play away! from Keen 4 onwards, however, it is an another story: with AdLib Soundblaster configuration, the sounds and music sound are almost modern, and so are the graphics apart from large pixels.

The true source of enjoyment, however, is the level design. And without a line of script, which means that you always have a change to suspect a trap before walking into it. Each level has an uniform theme, and they are fairly well planned with quite consistent overall difficulty scaling, and a lot of originality in their challeges. They also are full of bonus places, often well hidden. There even is a secret bonus level in all but one of the games, including the fan-mades! Also the monster design shows excellent imagination and sense of humour.

The game has a hardcore treatment of player errors: take a single hit, and the whole level has to be done again, and the whole game if you run out of lives. Only Keen 1, Keen 5 on easy difficulty and Keen 6 on easy or normal difficulty are fit for an average player this way. Instead, I recommend you abuse savegames if you want to play the games trough. Some Keen 3 levels are too hard anyway because you cannot save mid-level in the first three games (but there is a cheat).

The game has a scoring mechanism like minigames, but if you want to use it you have to define a bit of extra rules for that: There are levels wih more than one extra life, and collectibles are restored after restarting the level.

Overall, I recommend if you are more interested in exploring difficult, handcraft-quality levels than the mainline story.

Commander Keen is an amazing childhood game anyone could pick up and play. One of the best (and most difficult) platformers that I've ever experienced. Definately wish ID would reboot this.

Review Over Commander keen (I)

A world where Demiurg distributes matter by platforms.
Still a lot of things to learn from old games.

Just wow...
This I have not expected, one of the finest platformers of my childhood is now on steam.
Much recommended to anyone who would like to see what platforming genre looked like on PC back in the days.
Still stands solid today. Shame there is some outdated information on the introduction screen, other than that great value for money.

This was probably one of my first contact with computer games, for years I had only a few flashes of this game in my memory, and I had never found until today...

A nice retro platformer that stands up very well when compared to most of the newer games of it's genre. This game is especially great when you played it as a kid, and find out that it's still a very good game (as in my case).

Pros.
Solid platforming
Challenging levels
Different difficulty levels
Steam has the whole series, except for 3.5 and 6 (which is no real loss)
Option to turn off the music

Cons.
Those gorram dragonfly things
Music is god-awful

Again, if you're looking for 5 relatively short, retro experiences, definitely try this one out!

PS. My play time says 5 hours, which is my play time since I owned the game in my account (I was family sharing a friend's copy previously)

BETTER THAN MASS EFFECT

Commander Keen saved Earth a generation before Commander Shepard ever heard of the Reapers. Little dude built his own space ship out of soup cans. Shepard struggled building a fish tank. This 8 year-old kid was clearing out the Vorticon home planet while Shepard was telling everyone what his favorite shop on the Citadel was.

Shepard is a joke. Commander Keen is the real Spectre.

One of the icons of the DOS era. They label this as the "Complete Pack", but it is missing a few games (Keen Dreams & Aliens Ate My Babysitter).

This pack doesn't include Commander Keen 6 and Keen dreams is missing. Some people have been disappointed because those games weren'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 so frightening.

And eventually 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!

It still looks better than Cod Ghosts and it's playable. The best game of my childhood. I would save Gnosticus IV again.
