From what I know/observed myself:Shepardus wrote:What's the difference between Darius and Darius Extra?
- Excess lives are converted into handsome rewards at the end of the game, nudging players into completing it on one life instead of doing checkpoint milking against the final boss (mainly Octopus and Great Thing).
- The laser is more useful against bosses, particularly against Fatty Glutton.
- Stages are a tad bit harder on Darius Extra as far as I can tell, some zones have additional enemies and those blue turrets that fire a constant diagonal stream of bullets are quite a bit more resilient.
- I'm not entirely sure, but I think there might be additional orbs hidden in the terrain and/or the location of some of them changed.
