This mighty technician specialises in crowd control and area defense, handling multiple combat tasks simultaneously. This is primarily possible with his Servo-Gun ability. When activated, it locks onto enemies in a line of sight and automatically fires at them while the Techmarine continues fighting in melee or range. Furthermore, the Servo-Gun allows executing Gun Strikes without interrupting other actions._ **🟡 Changes from PTS:** - Fixed “Furious Gun Strike” prestige perk not activating properly. - "Revive Surge" prestige perk has been replaced with "Indomitable": “You become Invulnerable to Damage while activating Tarantula Sentry Gun” - “Chained Headshots" prestige perk now correctly increases headshot damage. - "Volatile Sentry" prestige perk damage boost increased from 40% to 1000%. - "Replenishing Salvo" perk cooldown reduced from 90 to 75. - Fixed “Lethal Perimeter” perk, it now correctly reduces the energy per shot for all types of Servo-Guns. - "Arc Cleave" perk damage bonus decreased from 25% to 20%. - “Explosive Enfilade” perk now works with Sanctified Wrath equipment. - "Augmented Tarantula" perk's damage boost increased from 25% to 30%. - "Augmented Tarantula" perk now correctly increases the turret's ammo. - "Methodical Destruction" perk now correctly debuffs enemies. - "Designated target" perk now correctly debuffs enemies. - "Omnissian Axe Deflection" perk duration increased from 5 to 10 seconds. - “Explosives Master” perk damage increased from 20% to 35%. - "Lethal Perimeter" perk using 50% less energy per shot instead of 20%. - Servo-gun damage now correctly scales with difficulty. - Precision Servo-gun damage reduced by 10%. - Bolter Servo-gun cooldown reduced by 20%. _Game Director’s note:_ > _We hope you will really like the new class. We've tried to make sure that this class plays differently from the rest. Thank you for your feedback on him from PTS. We've tried to address most of it, but there are some big changes that we didn't have time to implement. There will be more improvements and perks reworks in upcoming patches._ > ##### **New Weapon: Omnissian Axe** _With the Techmarine class, you will also get the chance to try out its signature weapon, the Omnissian Axe! This weapon is capable of dealing massive damage to both a single target with its standard attacks and to surrounding enemies with its finishing heavy attacks. And as a starting heavy attack, you can perform a powerful charge attack that can hit all enemies in its path. _ **🟡 Changes from PTS:** - Improved responsiveness of Omnissian Rush attacks. - Sweeping Whirl damage increased by 100%. - The third light attack in the combo now correctly breaks the enemy's guard. - "Armour Siphon” perk now activates properly. - Fixed the amount of HP which taken when using the "Iron Surge" perk. - "Executioner" perk duration increased to 5 seconds. - Added an energy explosion effect for "Explosive Strike" perk. - "Mighty Blast" perk second explosion deals correct damage. - "Expose" perk is now correctly applied. - "Cleaving Strike" perk no longer triggers environmental hazards explosions. ##### **New PvE Content: Tarantula Sentry Gun** _Techmarines can also locate and activate Sentry Turrets in PvE missions. These Tarantula-type emplacements offer automatic suppressive fire support against nearby enemies. Sentry Turrets have limited ammo and would go into standby mode after running out of it, but a Tech Marine can re-awaken them to restore their supplies._ **🟡 Changes from PTS:** - Fixed double HP and damage scaling by difficulties. - Increased spawn rate of turrets by ~50%. - _[Truncated at 4000 characters — full notes: https://store.steampowered.com/news/app/2183900/view/492717453033343660]_
