In short: this update nerfs SMGs, dual-wielding, and buffs sniper rifles and utility grenades so they are all a bit more reliable.
Dual-wielding walking speed penalty: 15% -> 22% (Nerf)
Pro90 weight: 3.98 kg -> 4.84 kg (Nerf) (affects movement speed)
Cyberspray weight: 1.47 kg -> 1.96 kg (Nerf) (affects movement speed)
Cyberspray price: $2100 -> $2600 (Nerf)
Hunter muzzle velocity: 10000 px/s -> 14000 px/s (Buff)
Awka muzzle velocity: 11000 px/s -> 18000 px/s (Buff)
Flashbang radius: 1250 px -> 2100 px (Buff)
PED radius: 700 px -> 1100 px (Buff)
Others:
You can now throw grenades further while running. Dashing makes them go even further.
Interference grenades now ignore armor. This means they are now extremely reliable for deactivating people's stamina for good several seconds.
PISTOL STANCE HITBOX HAS BEEN FIXED!!!
Previously, it was EXTREMELY HARD to get a hit on the pistol/smg-wielding opponents.
That's because the hitbox, while rotated 90 degrees, still didn't match the silhouette perfectly - e.g. on this screenshot, you could shoot through the opponent's arm like this without dealing damage at all. This has now been fixed.
