A new patch is finally on the beta branch. Most of my time has been spent making the controls (how you move and look around using the keyboard and mouse) smoother and more versatile. A few bugs where you would end up walking on the spot have been fixed too. The other thing is that you can now set the difficulty level of the bots to easy, medium, or hard.
The difficulty level covers two aspects of bots: reaction time and accuracy. On hard level, bots react instantly, and shoot with absolute accuracy (assuming the speed and direction of the target remains unchanged). On easy level, bots are relatively slow to react, and not particularly accurate at long range. Medium level is what bots have been on up until now. The default difficulty is easy.
