Alrighty, a bit late for the April 1st release, but here we go: ModOhFun 4.0!

Aside from minor additions, tweaks, and bugfixes, this'll be the true final ultimate release of ModOhFun.

ModOhFun! v4.0

- ADDED: An alternative Uber Cube mode! The Uber Keycard mode!

In this mode, you find halves of a uber keycard. Guarded by a group of elite enemies. If you find 2 halves, you can choose a spot to spawn a challenge of your choice, beat it to get a reward! Have at least 4 halves for harder challenges to be available, and have at least 6 for the toughest to be available!

- ADDED: New weapons!

- - The Cybie Head (slot 6)! Shoots plasma that leaves fire, and altfire that shoots projectiles that drops explosions!  

- - The Spammer Mastermind: An old but gold classic returns in the form of a weapon. Fire functions like a normal BFG, but without the projectile part. It instead immediately does the bfg tracers. Altfire summons a mini spammer mastermind ally!

- ADDED: Fat chaingun altfire. Slow firing, very accurate and powerful.

- ADDED: Starting a map in uber cube mode now displays the amount of cubes present.

- ADDED: Even more new sounds for weapons and monsters.

- ADDED: Lots of new pickup sprites for weapons

- ADDED: A few new ubercube challenges

- CHANGED: Numerous balance and other tweaks to weapons and monsters.

- CHANGED: Uber cube no longer spawns where BFG pickups are, because spawns would easily get stuck. The chances of them appearing where bosses (cyberdemons & SMMs) are higher now though.

- CHANGED: Tier 3 cubes now only appear where Spider Mastermind replacements are, as some challenges require a lot of space. 

- FIXED: Pressing use again on an uber cube while it was activating would cause it to disappear.

- FIXED: Lots of unpolished stuff with uber cube spawns, such as sometimes dropping two rewards or no reward from one challenge.
