You can find the complete patch notes below, with comments from our Game Director, Dmitry Grigorenko. ##### **NEW FEATURES** - **New Operation: Purgation** The Combat Squad Veridian must reclaim a Mechanicus facility in the Kadaku swamps. Communication is lost, and Nozick's Research is still inside the laboratory. - **New Feature: Battle Simulator** A new customisable battle arena in which you can practice, fighting various enemies and their combinations, as well as trying different weapons, equipment and loadouts. - **New Feature: New Loadouts & Perk Swapping** Players can now switch perk loadouts alongside weapons during a session. Perks loadouts are tied to your Weapon loadouts, so prepare accordingly. - **New Feature: Wargear 2.0** ​Expanded customisation options allow each class to wear multiple wargear at once, such as capes, iron halos and sensor antennas. > _We are going to continue to expand the customization system. With the next update we are also going to add robes and tabards to the shared wargear pool. But as in this update, players will have to earn their wargear. Also, more unique wargear items are coming._ > ​Known issues that will be fixed in an upcoming hotfix: - Iron Halos cannot be customised depending on the equipped Backpack for the Tactical & Bulwark. - Storm Shields cannot be customised if the Bulwark has an Iron Halo equipped. - Wargears are not available if the player selects an Armour Set Template. - **New Siege Content: Siege 2.0 Update** A massive update for Siege Mode. New items to buy in the Siege shop, fresh bosses, additional objectives, and a brand-new Blessings and Atonements system. Learn more in the dedicated part below. - **New Feature: Trials of Resolve ** New challenging Ordeals with unique rewards. - **New Weapon: Bolt Carbine One-Handed** New secondary weapon for Assault and Bulwark. > _Something more interesting than another sidearm is actually on the horizon 😜_ > - **New PvE Equipment: Pyreblaster Canister** A piece of equipment that functions like an incendiary grenade and requires to be shot to explode. - **New Heroic Items** Added 3 Heroic Weapons to unlock with Accolades: - **​Plasma Pistol **- Relic Battle-Worn Plasma Pistol - **Chainsword** - White Scars Chainsword (Block) - **Power Axe** - Encarmine Axe (Block) - **New Season Pass Content** Iron Hands Chapter Pack: - Techmarine Champion + Signature Omnissian Axe Skin - L&R Greaves; - L&R Gauntlets; - L&R Pauldrons & Decals; - 4 Successor Chapters ##### **GAMEPLAY & BALANCING TWEAKS** ##### **Firearms in PvE** - **Non headshot damage increased by ~30% for bolter weapons.** > _As we have discussed before, we want to close the gap between body and headshot damage for ranged weapons. The issue is that headshot damage calculation was very complex, because there were 2 sources of it: enemy damage zone sensitivity and weapon itself. Which results in weird multiplicative stacking that was very hard to manage and track. With this update we are doing massive rework and cleanup where we went through each enemy and adjusted its internal damage region sensitivity._ _In short, as a result: headshot TTK (Time To Kill) of all enemies should be the same, while non headshot TTK will be lower by 30%._ > - The global headshot modifier has been removed from Majoris and Extremis enemies and adjusted on Terminus enemies. - The headshot bonus now depends directly on the weapon’s stats, rather than on the target’s stats. - Weapon headshot bonus was greatly increased for all bolter weapons to compensate for removal of headshot bonus from enemies. - Known issue: as a result of the body shot damage rebalance, the gunstrike damage of secondary weapons shifted a lot. In some cases it increased and in some cases it decreased. This is not intentional and will be addressed in a hotfix. > _PS.
