I had some doubts about the GWX AI sensors in past version of the mod, but currently in the final 2.1 status I must say that it is fine-tuned to near perfection. Visual sensors in surface work as expected and I have yet to see a situation when I get detected and I was sure I wouldn't have been in real life.
Besides, OLC's environment makes the good even better, as it gives you dark nights but you catually can see enough to attack.

A step further and I couldn't play anymore withoput it
