Yeah I didn't mind though, I thought it was smart to keep using the scuba gear and also pretty atmospheric. I didn't want to punish you by spawning in more dudes to intercept your new route.
Incidentally, you might have noticed in the second mission, I was running into bugs where I could not spawn more OpFor - for example the opfor tab under individual units disappeared. You might also notice that remote controlling opfor units in the second mission bugged out and even though I could see through their eyes, the AI was still controlling all aspects of their movement. Was that the server struggling or something else?
