Incompatible with Quake HD Pack. Doesn't work properly in DP either -- the briefing room has a suitcase that presumably gives you a silver key to go out and select your skill level before hitting your bunk, but it doesn't seem to work as intended.

Go "skill 0", then map "sof1", or just noclip through the briefing room door. The initial firefight is confusing, as the enemies look identical to your team mates. Maybe this is intentional, you are fighting soldiers from your own army?

Anyway, you start with no weapons, so grab the nailgun and take the underwater passage to find SSG and rocket launcher, which acts like a key item in this case... you'll see.

Definitely worth testing! Some cool effects, like riding in a chopper and jungle at night theme.

Actually, the silver key is supposed to be in the vent above the filing cabinet. I already checked it before reading the spoiler in the readme, it doesn't show up there, either. :-(

Works correctly in DirectQuake ^_^

the only two problems i had were: 1. with the chopper at the beginning. i 'got stuck' if i didn't jump immediately and repeatedly, once the map is visible. 2. the 'push' function under water forced me past the alcove with the red painted face. i had to noclip into it. everything else seemed to work with the Requiem engine through the Quake Injector.

overall, a nice concept. i thought the fiend & shambler skins were well done! i made sure i had sof2.zip installed to 'complete the mission.'

The only problem I had when running this in Ironwail was the water push mentioned above. I did manage to use a rocket to knock myself into the necessary side passage, just as a challenge to see if I could manage without noclip. :-)

Might be something there that only worked at low framerates?

Just press "JUMP" button while swimming underwater tunnel
