While prone with any weapon, with or without a bipod, deploying and undeploying the weapon will push the player around, mostly backwards.
- Legacy ID
- Weapon Stabilization
Go prone and press the "Deploy Weapon" key multiple times while holding a weapon. The unit should move backwards slightly with each consecutive deployment.
The exact direction of the movement appears to vary depending on the type of terrain you deploy on, but deploying while prone on any flat surface will push the player to the rear and off to the right slightly.
As we can see in the dev branch changelogs (http://forums.bistudio.com/showthread.php?149636-Development-Branch-Changelog), the developers still tweaking the weapon depoloyment.
I really hope, they pay some attention for that minor issue.
