I have upgraded Firebreak: Strike Team to Unreal Engine 4.20 and that version is currently available for download. I are currently working on the engine upgrade to version 4.21.
Notes:
The version available still has various debug and testing features disabled. *Helicopter collision damage is off at the moment
*There is a test map in the rotation with a 5 minute timer, and the fire is currently disabled. This is to allow for testing on our current bug fixes around multiplayer vehicle physics.
*For a full list of test conditions visit our discord at: https://discord.gg/cGKNcJ8
