General -

• The Health meter can now be overfilled up to double
  

These changes should fix the survival gameplay loop of constantly juggling enemies just to be overwhelmed by them.

Additionally, the secondaries and crit boxes make the game much more engaging and fun to play.

Special overfill also adds more depth to Rogue and Campaign modes.
