As per the title, AI patrols do not see you if you are travelling in a vehicle. You can happily mow them down one by one whilst they are completely oblivious to your presence. Also, several of the attachments actually destroy the weapons and make it disappear from your inventory. If I knew it was going to happen I would have made a note of exactly what gun and attachment it was. Also some attachments nerf the gun totally. Adding an SD to a G36 makes it zoom in like a sniper rifle but with no crosshairs. And I mentioned this before in another thread, but adding SD only alters the sound range for players, not for zeds. The acoustic range of an M14-SD is still the same to the zeds as an unsupressed one. Ditto every weapon you add SD to And none of the sniper zoom optics work with NVG - making night time pointless. More spawn points are seriously needed. One HALO drop point ? Why not put some on the western side of the map too ? It soon gets repetitive, halo spawn, head straight to NE airfield. Die. Repeat. More fuel points too.
