Such is the case with XBLA's Bangai-O HD: Missile Fury. Any illusion of narrative has been stripped away entirely and only pure, unadulterated shooter insanity remains.
Under the normal conditions of a shmup, surviving Missile Fury would be impossible. Thank God your mech can also freeze incoming bullets, dash and counter attack within a certain range. The latter is key to survival, as most levels are so preposterously overloaded with enemy fire it can be next to impossible to keep track of where you are. Essentially using your counter attack fires a ton of projectiles but leaves you vulnerable while a multiplier builds. Counters will clear the screen of whatever's closest to you, and if you're skilled you can use this brief window to dash away and plan your next attack, though doing so is easier said than done.
Treasure is at its best when it really gets unhinged, twisting the shooter tenets in some funny and unexpected ways. My particular favorite is a stage whose enemies can only be defeated by bouncing giant soccer balls into them. In another instance, you'll navigate a small, mazelink track completely covered in vicious but dormant enemies. (You can imagine what happens when you screw up. Think board game classic Operation.)
The developers like lulling you into a false sense of security as well -- if you're stuck at what you think is the final push of enemy assaults, chances are there's probably something even bigger and more ridiculous waiting to ambush you immediately afterward. Shmups are hardcore enough, but Bangai-O HD: Missile Fury somehow feels like a niche unto itself. At least death is served up à la carte, so you can move between stages at will if you die three times.
Just so we're clear: You'll be dying a lot more than that.
