I played this when it was brand-spanking new, it still holds up today as one of the best PC platformers.

Being one of the first games, I ever played, Commander Keen is the PC equivalent of Super Mario. You jump, run and shoot your way through 2D levels, avoiding traps, gaps and monsters.

Being an oldschool game, the difficulty is sometimes a little bit silly.

While 4, 5 and 6 had mid save options, in 1 - 3 you could only save in the main area, not inside levels. Combined with nearly unkillable powerjumping...we called them Zombie kangaroos...this game is quite a number of difficulty.

After the 4th part you also got a difficulty option, that enables traps and increase the amount of monsters.

Beside that, the game has a little ongoing story about the main character, explaining him and why he is doing all that (genius child, build a blaster and a rocket ship with parts of his familys home).

(PS: Every game has at least one hidden area and level)


The bad part about the bundle (yes its 5 games in one), that it is missing the last 2 games. 6 was a special limited edition (who limits a game???) and 7...we dont talk about 7.


The story doesnt end with 6 or 7 ether, so fans made Keen 7 (denying the existence of the real keen 7), Keen 8 and Keen 9, who look quite decent and end the Keen story for good. Check it out on Youtube.

Play as commander keen! As he avoids terrible vegetable aliens and catholic priests out to molest him. This game was a revolutionary stepforward in computer graphics, as Id software found out a way to create parallax scrolling for the PC. PC gaming was never the same afterwards.

I'm not too keen about this compliation. While I could give credit to ID for creating one of the first PC side-scrollers, I will say that this has not aged well at all, and not only do you get killed in one hit by everything, but there is also absoultely no way you can give yourself a health powerup that can give a little leeway towards being damaged by enemies. The backgrounds in episodes 1-3 are incredibly dull, and it feels like I'm playing a launch Atari 5200 game. To make matters even worse, you have a lives counter, and in a game like this, you will get so many game overs that you will want to destroy your computer, and play the Japanese Super Mario Bros. 2 on the NES instead. If you want an old PC sidecroller really bad that doesn't tear you into pieces and is vomit-inducing, I would go with just the original Duke Nukem, and avoid the second one, as that one is unforgiving compared to the first. If I were you, I'd buy Sonic the Hedgehog, or any other Sega Genesis classic here instead, you won't regret it.

This is a great platformer that was released a long time ago and re-released on steam.
I owned them back in the days and I played them to death, so I was happy to see them on steam as well.
The only downside : keen 5 and 6 are sadly missing..
BUT it has a pogo stick!
10/10 would pogo again

Holy frudpumpfles this game lets me blast those Shikadi into the next dimension, how froopy is it that they give you a pogo-wogo?. Zarkin' frood this game is good. As I was presidenting the universe one day on the heart of gold, somebody handed me a flopette disk containing the words: "Are you keen?". Now usually I'm too zarkin' busy to dig anything but myself babycakes, but when I loaded this humdinger of a diskette into my Zopflmonitor 2, I knew I was in for a real treat.

I had a blast blastin' some bloogs, you dig?

10/10

Commander Keen is, quite simply put, a masterpiece of the early 90's PC sidescrolling platform genre. Challenging yet fun gameplay that features bouncing around on a pogo stick and zapping aliens with a raygun, what more could you ask for?

Unfortunately, despite it being called the "complete pack", it only contains the first five episodes, 'Aliens Ate My Babysitter' and 'Keen Dreams' are sadly missing from this collection. Still, despite their age, the games that come with this pack are still fun to play, and it's very highly reccommended to people who love platformers or grew up in the DOS era of PC gaming. 4.0/5.0

Growing up most kids had a NES, I had DOS and Commander Keen was my mario brothers. This is still a fun game that will bring back memories for those who grew up playing this game.

Played Commander Keen in the early 90's? In dire need of a nostalgia trip? Buy this game pack today! Works flawless using DosBox. Be aware that this game pack neither cointains the sixth episode, Aliens Ate My Babysitter, nor Keen Dreams though.

Pros:

-It's a classic.
-Bobby Prince musicz.
-Doesn't require DOSBOX to run.

Cons:

-I wish I was 5 again.

I used to pk unzip,dir/w, and cd.. when I was 5 years old instead of slapping cartridges into a shoebox. The PC Masterrace was strong in me at a tender age and ID software, Apogee, and Epic Megagames are to blame.

Golden Platformers...if only all 7 were together.

So before I begin, this pack is missing two games: Keen Dreams and Commander Keen 6: Aliens Ate my Babysitter. I know there's legal reasons behind the games being absent, but it would have been nice.

Before they unveiled DOOM and changed the video gaming industry forever, the creative folk at Id put together these humorous and quirky platformers. All five CK games are brilliant in their layout and execution, but they're also hard (4 & 5 have an easy, normal, or hard setting while 1, 2, & 3 don't). Any platformer or retro game fan needs to buy this pack. It's basically $1/game and Keen 4 & 5 are WELL worth $5 each. You owe it to yourself to watch the silly story unfold and enjoy the silly 1991 humor the game brings to the table, and since this uses DosBox's emulator, the music (only in 4 & 5) is also fun to listen too!
