*The game is winnable
*New armor system:
~Armors provide different amount of protection from different damage types (physical, fire, electricity, etc)
~Armors can be damaged, which makes it less effective
~Armors are named "Name [D%, AP]", where D=Durability, AP=Damage reduction (vs physical)
~Armor stats are shown in the character info lines
*New armor type: Asbestos suit (very good against certain damage types, bad against physical)
*New magic system:
~Scrolls (now called manuscripts) can be studied to be identified or memorized (to cast them at any time)
~Chance to identify or memorize depends on the language ability
~Casting spells from memory drains Spirit Points, it can also cause miscasts with negative effects
~The 'R'-key is used for studying texts, 'x' for casting from memory, and 'X' for casting from manuscripts
*The melee abilities are merged into one again, and vice versa for firearms (the split didn't add anything to the game)
*New abilities:
~Spirit - increases max Spirit Points
~Arcana - gives better chances to cast spells from memory without failure
~Technique (melee) - Chance to get free turn (light weapons), full damage (heavy), or random bonus (medium)
~Reloading - Chance to get a free turn when reloading firearms
*7 new monsters
*6 new potions
*"Treasure rooms" with armor and ammo, or scrolls and potions, that are usually secret.
*First aid can not be started if a monster is seen, and is automatically aborted if one appears
*Special rooms occur less often
*Less pop-up descriptions when entering special rooms (I found them extremely repetitive once you know them)
*Mi-Go electric guns cause paralysis
*Added missing messages for wielding and wearing things
*Attacking an unaware monster in melee makes it aware even if you miss
*The Incinerator's dmg description is "?" (less misleading than showing the projectile impact damage)
*Removed some stuff from the character info lines to make room for new things
*Pools no longer slows you down (it didn't work very well)
