GAMEPLAY
As a pre-release beta, the following changes can be previewed offline with bots:
- Smoke grenades now have 10 unit radius when deciding if they are close enough to a fire to extinguish it. This helps reduce the number of ‘gaps’ between flames which could cause a smoke grenade to not detonate.
- Additional changes to smoke grenade detonation to make smoke/fire collision more predictable in areas with rough terrain / ledges / stairs.
