It’s not really beta quality. I hopped on with my brother just to see if I was interested in the game (we both played black ops, the original back on the PS3). It was actually extremely stable and pretty fun. He noticed a UI glitch but … it’s not like there was even a feedback or bug report button.
It’s just early access with the disclaimer there might be something wrong… Which isn’t that different from buying a release day game anymore unfortunately.
