Tyrian for iPod/iPhone is a revival of the 1994 cult classic shooter by Eclipse Productions. The game is based upon an open source version of the original called OpenTyrian. I should mention before getting into specifics that due to licensing differences, you will have to download some data files in addition to the app itself. This is perhaps due to the game’s use of files under a GPL license. The whole process only took about a minute on my wifi connection, so it shouldn’t take too long for most. So how does this classic shooter translate on the iDevice? Read on!
