It ended up being ported to several other systems, and in some cases, big changes were made.
So which version do you prefer?
- Atari 2600. The original. One of the first games with changing enemies. The way the aliens warp in is awesome. The aliens that split in 2 was a huge surprise the first time you saw it. It's fast and very fun.
- Atari 8-bit. Exactly the same as the 2600 version. Which is lame. So much more could have been done here.
- Intellivision: Truly an awesome port. They added a planet to the background and a boss level. But the game is slower and a little less colorful. Still, that boss is so cool looking.
- TI 99/4a: Came on cart or disk and the disk version had speech! This one is similar to the Intv version, but the aliens are much more detailed and crazy looking. In my opinion, probably the very best TI 99/4A game. It's crazy fun.
- VIC-20: Exactly the same as the 2600 version, but with one huge improvement. If you shoot the bottom-most alien, the others will move down and start firing. An amazing technical achievement on this limited machine.
- Odyssey 2. They tried. But the limited hardware really shows here. It's slower, and only 2 aliens at a time. Still, it's a lot of fun.
- Commodore 64 - a mix of the Intellivision and 2600 versions. Really great game. Love the boss level.
Vote and tell us why.
