I played them and recorded some footage without any commentary that i will upload later, but i found game breaking bug on mission 3 when playing on brutal.
It's on the spawnWasps Trigger that generates new workers for the enemy, when you play on brutal it generates them every 0 second. I just changed the value to 200 and it worked.
Hmmmm, that should be impossible. I don't actually use the 4th parameter for anything, the third one is for "brutal". It works for me, and my testers didn't report anything on that difficulty. You're just selecting the difficulty from the mission briefing right? Do you have a video of the bug?
Only 3 of 14 missions are released so far. I've been slowly chipping away at this for a while, and hope to actually finish it. None of the voices, gameplay and terrain is set in stone. I hope to keep improving the campaign over time. Still looking for development help if anyone's interested.
