ZAXXON (1982)
by Mark Nobes, chief editor
The video above features just about every version of the game you care to mention - plenty to keep you amused for a while, at least!
The screenshot (left) is from the superior arcade version which was released by Sega in 1982. This
game was very exciting at the time due the use of simulated 3D graphics from a third person viewpoint. It also featured shadows, which was extremely rare in the early 80s.
The game used a type of Axonometric Projection (the name Zaxxon was derived from Axonometric) called Isometric Projection. However, the Atari 2600 and Intellivision versions were displayed in a standard 3D mode, and this was most likely because these machines weren't technically capable of running the game with Isometric projection. I suspect that there is a programmer out there who may have disproved this theory, though, as there is an unofficial version of the game on a Radioshack TRS-80 computer (see the playlist above) which is quite a feat.
Zaxxon was available for most home computers and consoles and proved to be
extremely popular. A sequel, Super Zaxxon, was also released in 1983,
but didn't go down as well as it proved to be rather too difficult to play - at least, it was on my Atari 800XL.
The original Zaxxon looked very impressive on my Atari 800XL, but I always found it frustratingly difficult to play as it was very hard to judge what altitude you were flying at!

Atari 5200/XL/XE Version
Atari XL/XE Version
I remember playing this version in 1984 on my 800XL with a school friend (it was my final year in school), and he was absolutely gobsmacked by the graphics, more particularly so because he owned a ZX Spectrum. The Speccy version was, unfortunately, not very well executed and probably one of the worst of all the versions available.
I really enjoyed playing Zaxxon, but as I mentioned above, I was terrible at judging the height of the spacecraft. The Atari version was also extremely fast, which made it even more challenging. However, with a lot of practice I found myself completing the levels more easily. The sign of a good game is one you keep going back to, despite your frustrations, and as 80s computer games go, Zaxxon was certainly one of the most impressive of the decade.

COMMODORE 64 (C64) VERSION
Graphically, the C64 version is actually more appealing than the Atari XL/XE version, although the Atari version is definitely quicker due to its slightly faster CPU. Of course, I'm at risk here of reigniting the old rivalry between the two machine's users, but that's my take on it.

MSX VERSION
Well, I quite like the colourful graphics, sound effects and music in the MSX home computer version, but it's just a shame that the scrolling was so juddery (this problem also exists in the Coleco/Colecovision version), otherwise this had the potential to be the best version of all.



SUPER ZAXXON (1985)
Personally, I found the original Zaxxon game far better than this sequel which was released in 1985 by US Gold. The Atari XL/XE version featured ghastly colours and very difficult gameplay. However, the shadow effects are quite decent.
I remember the excitement of seeing the tantalising inlay card, which tempted me to buy this on cassette as a treat during my first year in work - I kind of wish I hadn't bothered!
The C64 graphics certainly look more appealing.
