Classic arcade games have some appeal to me. I grew up playing some but I have to admit, I hadn't heard of Tyrian until it was shown to me. It's very old school and quite fun to play too. Tyrian is a vertical scrolling shooter game and is very arcade like in it's graphics. Forget the Hi-Res graphics, this is old school.
There are two modes of play within Tyrian - Full game and Arcade. With Arcade mode, you can't purchase any system upgrades, like rear guns or sidekicks. Instead you get these by collecting power-ups when you destroy enemy spaceships. Your weapon selection is also a bit limited. In the Full game, it is exactly that. You're playing the full story mode, with plots and hints. You will be able to upgrade your ship using the coins you collect during game play. Ship upgrades include rear guns, multi-directional cannons, bombs and more. There are sidekicks that can be purchased too to give you some extra help.
It's a fun game to play. I haven't started the full game yet. I enjoy just playing the arcade mode. Perhaps, one day I'll start the full game but the arcade mode is fun enough for me.
Tyrian is available for the BlackBerry PlayBook, Z10 and Z30 and is free. I have heard from the developer that a user of the game on the PlayBook successfully used a Bluetooth keyboard for controls. The onscreen controls could perhaps be cosmetically nicer to look at but I guess that's what you get for old school. These onscreen controls can also be adjusted and placed where your prefer too. If it came to the Q10 and Q5, being able to use the keyboard as controls would be awesome.
