Okay, I've been playing this map, and while good on paper, there's been a lot of issues I have with the level that, frankly, made it unplayable. So I've decided to do some changes:
1. Cleaned up the level coding.
2. Implemented objectives which explain what to do, especially since nobody will expect the massive army near the end.
3. Trying to find a purpose for the Tunneller and the Armageddon Spell.
