I played the first part for a while, but wasn't particularly impressed, and it was just too difficult for me and I quickly got frustrated. Part 2 does a lot better and although it remains a challenge, it is not as difficult as part 1. After an introductory tutorial, varied levels await the player, each with their own final boss, which I particularly liked. But the best thing is still the speed, because System Critical is an incredibly fast shooter. The new secondary weapons and different main weapons are really fun and the jump and run elements are better thought out and the checkpoints are better placed. Great shooter, with lots of setting options.
