With the Hotfix Update on July 30th, we’ve updated the game with a set of improvements and fixes, with a particular eye to improving Melee combat. Take a look at the list of changes below and give us your feedback on the Dirty Bomb Forums after you’ve given it a spin for yourself!
Balance Changes
The timings for the damaging portion of Melee Attacks have been updated to more closely fit the weapon animations
Previously, the hit duration was very forgiving, meaning that weapons could still potentially deal damage well after the initial strike
This also means that turn-speed limitations can end earlier, which gives players more freedom when performing melee attacks
The allowed turn angle when attacking with melee weapons has been significantly increased and now scales with weapon damage
All melee attacks have been improved, and the lower-damage, high-speed attacks (Primary attacks for the Beckhill and Stilnotto knives in particular) have had their turn speed massively increased
Bug Fixes and Other Changes
Blocked the KILLPARTICLES command from being usable
Fixed issue with some loadout cards having missing first person arm textures
Fixed certain account levels being unable to see level restricted servers in the browser
Fixed a bug where players were prompted to select a Merc in the tutorial level
Fixed a bug with Phantom where he couldn't use Refractive Armor after repairing the EV
In the past week, the matchmaking back-end has been updated to prioritise more balanced matches over quicker matchmaking times
This should result in longer queuing times, but better matches
