Now the game is Really Ready. I previously gave it a negative review due to some bugs and the AI of both allied and enemy bots, but over the past year, several updates have noticeably improved it. Although allied bots are still quite dumb, the overpowered behavior of enemies—who could spot you through tiny gaps and shoot through walls—has been fixed. New weapons and sights have been added, the controls have been slightly adjusted, a couple of new mechanics were introduced, and it seems like a few bugs have been fixed as well.
Overall, it's now the kind of game you just want to get lost in.
