community map - arena by Richard0820 skin tech: depolarization - gain +300 damage or -50% damage if a mobs has died in last 5 seconds CPT triggers if you have above 90->85 energy CPT skin graphically indicates when CPT is active mass-energy defense reduction is 66->50% new level load display animation draws the outline of the new map only on reactor and final levels choose MINIMAL HUD in settings to disable (or enter testing mode) enthalpy spawns heals on mobs death with a 5% chance this is roughly an 80% increase in spawn rate mass production spawns a few ammo and heals when you first get it paradigm shift 6->4 health removed incendiary ammunition drone and shotgun explosions are 30% bigger Zectron super balls do 75->90% more damage and drain 25->20 energy on hitting player fixed bug with optical amplifier and cloaking field plasma ball can pick up power ups when out of energy, like other fields fixed bug with not hiding mouse
