One of my favorite games on the XBox 360 was John Woo's Stranglehold, my older brother took the console with him when he moved out, and I'm pretty dissapointed when Stranglehold is not available on Steam. I find this to be fun cheaper alternative, with the intense joystick gunplay, slow mo mechanic, but to me my favorite assest of the gameplay is the tight and terrific triple jump, with combined with the slow mo and walljumping makes dodging almost as fun as the shooting.
It's a pretty simple game, however full of personality from a fun main character; Wyrn, who has fun one-liners. It's a very self-aware meta game. Each level I played so far each have intersting and unique obstacles to give variety and engagment.
This is a short game, though I'm not finished the game because I like speedrunning along getting S-Ranks, and grinding to get better stats, so I'm taking my time with the game. If you enjoy Practice gameplay. There's four mode of difficulties, so I'm sure anyone can play easy mode and breeze through the game, however I'm not sure the amount content in the game would be enough for most people, I bought this on a sale, and it's one of the best purchases I got from Steam, though 5 bucks is not that much anyway.
I have a few problems with the game, no health packs at all, which it's a bit unfair, your expected to beat the game without dying, I think more than one death lower your score. Though once your max your stats, I'm sure it won't be that difficult, at least on Normal. Also really only Katana feels like a secondary weapon that's useful, I feel the twin pistols is much better than the shotgun and rocket launcher, so I suggest just buy more health and energy upgrades.
