Summary
Often considered best part of the series. It's my favorite Keen game.
The Good
The graphics! The first trilogy "Invasion of the Vorticons" had simple graphics that just did the job. From part 4 however, an all new graphics engine is used. This new engine vastly increases the graphics. Instead of the simple graphics seen before, this game has beautiful comic-style graphics that are much better than most of Apogee's platform games of that age. The story continues as eight-year old genius Billy Blaze picks up a help sign from outer space. Once again he transforms into Commander Keen to go on another mission. His mission leads him to the Shadowlands, a diverse landscape on the planet of Gnosticus IV. This diversity makes it my favorite Keen. While most games in the series have more or less similar worlds this game has levels ranging from desert castles and Aztec-like pyramids to forests and caves. There is even a diving level where you meet the legendary Dopefish, one of gaming,s most beloved enemies. This brings me to another strong point of the game: enemies. You will meet many dangerous creatures such as the Poison Slugs, Skypests, Inchworms and many more. Also there are some friendly characters that could be useful such as Princess Lindsay, Bounder and the old and wise men you need to rescue at some levels. Another vastly improved point is gameplay. While the first trilogy had smooth gameplay for it's time, in this one it's even better. Jumping is much smoother now and thank goodness they fixed the annoying CONTROL+ALT shooting method (it's still optional, but what loser wants it anyway?). New gameplay twists include shooting in different directions, climbable poles and clinging to ceilings. Also included are some fun twists such as a secret level, a method to make Keen "moon" you and a pong-like mini-game which are nice. Another new feature that I missed in the first trilogy was sound card support. There's music now!
The Bad
It's a bit too hard at certain points, even when in easy-mode, mostly because you can take only one hit and you'll die. This isn't necessarily a bad thing for some people, though .
The Bottom Line
This has been improved so much from before that even those people who didn't like the first trilogy mat still love this (the same counts for part 4 and 5, since they use the same engine). Of all classic Apogee platform games this is probably the best one. You'll love it, it's brilliant! (This is not a surprise if you know that the same guys made such great 3D-shooters such as Wolfenstein 3D, Quake and, off course, Doom.)
