Changelog:

[Features]

• Added break action shotguns
• Added regular checks to kill enemies that may have fallen through the map and prevent mission completion

[Physics]

• Raised the stiffness of player arms, no longer as wobbly with fast movements or strong forces and no more shoulders at ear level

[Weapons]

• Three new double barreled shotguns
• Boomstick (regular double-barreled shotgun)
• Sawed-Off (double-barreled shotgun with sawed off barrel and stock)
• Shorty (double-barreled shotgun with sawed off stock)
• Overhauled the 50BMG and 100BMG Sniper Rifles visually and fixed their recoils (they really kick now)

[Changes]

• Enemies stand up more reliably, no more floating up from their pelvises
• Sniper rifles can now have more than a single instance in the level and are no longer removed from the weapon wall after picking up one of them (dual-wielding 100BMG?)
• Improved the visual clarity of scopes when viewed close-up
• Lowered player body a bit so your neck is actually visible and not stuck inside your torso

[Fixes]

• Fixed infected waves
• Fixed zombie attacks not working
• Fixed tons of shiny objects in the Office and Lobby levels
• Revolver casings no longer fall through the floor when ejected
• Fixed shiny dismembered limbs (probably, I haven't encountered them again)
• Fixed missing shopkeeper skins

[Known issues]

• Enemies without one leg will still try to walk, although not very well
• Sometimes enemies refuse to get up after falling and try to attack you while lying down
• Melee enemies with a knife seem to get stuck on walls in the Office level. Not sure what's up with that but I can't seem to reproduce it reliably.
