Underrail 1.1.0
| Release Date: 9 July 2019 (experimental branch) | Summary: Game speedup, mechanics/item tweaks, graphics updates, bugfixes | 
| General
Added the ability to speed up the game while out of combatAdded achievements to the GOG Galaxy version
 Feats
Kneecap shot bleeding percentage no longer scales from perception, but base bleeding damage percentage changed to 125% (up from 75%)
 Mechanics
Unarmed and fist weapon attacks now incur 140% of target's damage threshold and resistance (up from 125%)Increased the damage reduction factor of resolve against neural overloadResolve will now reduce the damage received from doppelgangersChanged the way the burning damage stacks (in cases when it stacks) - the new burning time left equals either the time left of the existing effect or the duration of the new effect - whichever is longer; the old and the new periodic damage are adjusted so that they produce the same total damage over time; one of the major effects of this change is that you can no longer increase the amount of original damage by constantly resetting the timerSeparated fear effect caused by burning into a separate status effect and limited it to 2 turns regardless of how long the burning lasts (or if it's extinguished early); this will prevent the fear from lasting too long either from a long burning effect or because of the burning effect being refreshed; also this fear only occurs when a non-burning target is ignited and not when burning is being prolonged/refreshed
 Items
Throwing nets now last up to 2 turns (down from 3) and have a cooldown of 4 turns (up from 3)Bullets have new iconsIncreased the chance to entangle enemies when firing acid blob pistolIncreased the chance to freeze enemies when firing cryo blob pistolsReduced the chance to ignite enemies when firing incendiary blob pistol; the total burning damage done from igniting the target will remain the same, but will be spread over more turns (one turn per  each80% of the original damage repeated)Reduced the weight of chemical ammo
 Nice Things
Containers that you opened once will now have darker labelsOrganic enemies that die while burning will now be smoking and appear charredHE grenades and some other explosions will leave temporary marks on the groundGas clouds will now fade in/outNew barrels
 Bugs
Fixed the bug that would allow player to cancel leveling up without being able to reattempt itFixed the problem that caused the items to take up weird positions in the filtered inventory when the player attempted to reorder them manuallyCut Throat no longer bypasses stun immunitiesCorporeal Projection feat now has a proper icon (instead of using the one from Fast Metabolism)Throwing knife will now again properly play impact sounds and effectsFixed the bug that caused expertise to add the damage bonus for each separate mechanical damage listed for the weapon, instead of just once (you thought I'd never find out, did you?!)Fixed the hole jump crash in InstituteHeavyweight will now always apply before Critical PowerCertain giant appendages can now be hit by cryokinetic orbChanged the way the cryokinetic orb shards interact with the orb impact tile so now the creatures occupying the tile can also get hit by some of themPunching bags will no longer bleed when you punch themGlobal entities (those that can travel between maps) will now also have their suspicion meter drain with timeIncendiary chemical pistol burning effect will now stack damage with existing burning effectFixed the Nimble bug that would in certain situation give bonus movement pointsVarious minor map and dialog bugs
