TWICE now I have loaded and continued a campaign game only to find that I suddenly have a NEGATIVE AMOUNT of NANO CATALYST equal in number to the POSITIVE AMOUNT I had collected when I had last reached a checkpoint and turned the game off. This wouldn't even have been an issue if the game allowed me to save when I wanted to, because then I could have applied my upgrades and saved afterward, minimizing the loss of hard-earned points, but instead, this archaic saving method has screwed me over and over again, forcing me to kill even more aliens just to get back to zero before I can even start to make any progression. So, for example, instead of being able to upgrade the Nanosuit's stealth to help me survive a harrowing fight against the Pinger in the Central Station level, I instead had to fight with a weak-ass suit AND work my way up from a -15,000 Nano Catalyst score, points which I had already earned but lost forever thanks to your crappy checkpoint system and your piss-poor Quality Assurance.
I thought I had enough problems with the broken, glitchy multiplayer, but now this new problem has just about ruined my experience with the campaign, which up until now had been largely positive. I don't even know if I will bother finishing the story or just trade it in tomorrow, because a buggy mess such as this has no place being on store shelves. How the heck did this game pass certification?!? You should be ashamed of yourselves. One thing is for sure, you won't be getting my money again.
