Thanks, Shadow!
I did think of a bug this morning without even playing the level, which will need to be fixed. You can actually get the fog in the secret area all over the map if you leave before it ramps down during the room transformation. I thought to myself that I hadn't put a fail safe in to prevent that and lo and behold yep it's a bug haha.
I didn't even know if I had shipped that ceiling gap in the first bunker area... I just noticed it one day. I somehow made a brush entirely caulk :/.
Haha, yeah that officer uses the SurpriseAttack behaviour which may need tweaking, but I kind of made him a 'mini-boss' of sorts as he runs away from you as you enter the radio room.
The barricaded door is indeed a fair bit wider now to allow for grenade tosses in there. I've scripted it so the AI respond as well and you're able to kill the officer in there with it.
I did add a health flask in the first courtyard building as well just to help players out before the assault.
I made various small and insignificant aesthetic changes like improved the railing decoration on top of the dark stone building after leaving the bunker but they were just nagging me and not much of an issue tbh.
