The Autumn Update has just been released, with many fixes and improvements. Below are the highlights of the update, and you can find the full list of changes at the end of this post. - Added new "Blueprint" type of items, which are needed to unlock crafting recipes and make use of Alien materials. Blueprints can be found as loot or some can be bought from traders. - Railgun rebalance: Railguns now behave more as expected as they can hit multiple targets rather than disappearing on the first hit. - Grenade aiming improvements. - Broad spectrum antibiotics and antibiotic glue balance passes: BSA has a more universal effect, glue is more situational and has drawbacks. Infections are not as easily cured or prevented anymore. - Several fixes for the ongoing multiplayer exploits. - A lot of bugfixes. Be sure to update your game to be able to host and join multiplayer servers. We hope you'll enjoy the update! _v1.10.5.0_ **Balance:** - Railgun rebalance: The railgun has been deemed on the weaker side by the community. It has been given a satisfaction pass, where now the high-power shell behaves more as expected, capable of penetrating multiple limbs or submarine walls, dealing more damage. - Broad-spectrum Antibiotics now affect all limbs with infected wound with one application, but cure less infection per limb. Base prices for Plastiseal, Antibiotic Glue and Broad-Spectrum Antibiotics have been adjusted. - Antibiotic Glue is now less effective on healing burns, bleeding and infections and inflicts organ damage even with successful application (and even more with failure). - Added a pass to make grenades more easy to aim (and less likely to always hit the wall in the back due to excessive sliding/rolling) - Reduced and equalized throwforce of most throwables (grenades, explosives) to 3.5 (some were 3.5 already, some 4.0). - Add angular dampening on grenades to reduce excessive sliding/rolling. - Frag grenade now uses a rectangular body instead of round/capsule, to avoid rolling too far (more in line with other grenades). - Reduced throw force when aiming throwables downwards. - Lower the rate at which skyholder artifacts and portable pumps drain water (both were way too effective for managing leaks). - Made all variants of fractal guardians vulnerable to EMPs. - Security NPCs on submarine encounters are now better armed, with weapons fitting the faction. **Blueprints:** - Added new "blueprint" type of items, which unlock crafting recipes. - Three new alien material blueprints: physicorium, dementonite (gravity) and incendium, which unlock relevant (ammo) recipes. - Alien blueprints need to be researched at a Research station. - Merchants of all factions now sell item blueprints fitting to the faction's identity, locked behind reputation. **Miscellaneous changes:** - Made vent sounds a bit more quiet. - Made crate shelf and makeshift shelf container UIs vertical to match the look of the sprites. - Made some items be attachable only to the floor. - Planters cannot overlap, and attach only to the floor, rather than attaching to the wall. - Makeshift shelves are attached to the floor. - Outpost NPCs react to players dragging other outpost NPC's corpses. Normal NPCs flee, security arrests you. **Fixes:** - Fixed gaps significantly slowing down the flow of water, especially when water is flowing up through the gaps. - Fixed PvP outpost selection not working reliably (when you selected some specific outpost, it was possible for some other outpost to get selected regardless). - Fixed bot AI not running if a bot below 0 vitality is forced to stay unconscious with e.g. adrenaline or talents. - Fixed incorrect offset on the light that renders on a boarding pod that's in a loader. - Fixed defense bot only escaping if it attemps to fire it's weapon and fails due to being out of ammo, but not when it doesn't have any ammo available. - Fixed outpost NPCs sometimes spaw _[Truncated at 4000 characters — full notes: https://store.steampowered.com/news/app/602960/view/506214297188171877]_
