just do it

game black screens on startup

Story gave me secondhand embarrassment listening to the anime stereotypes talk non-stop.
Gameplay is shallow and I mean SHALLOW. Weapons sound pathetic and variety is extremely limited.

Served a purpose existing before Armored Core 6 hit the scene to scratch that itch as about effective as smoking dregs out of desperation. Now, comparatively, since they're both similarly priced, you would be completely brain-dead stupid to ever buy this game over Armored Core 6.

If you're really that interested, just go on Youtube and watch a 'no commentary' longplay of it, just be prepared to hit the right arrow key through every cutscene (which will eliminate about 70% of the game's runtime).
