This update introduces:
- New rifle grenades
- New Soviet flamethrower

A number of these changes have been shaped by your feedback during our recent Experimental Branch tests. Thank you to everyone who jumped in, shared feedback and helped us continue refining Update 21 ahead of release.
Alongside all of this, Update 21 includes fixes and improvements across gameplay, weapons, vehicles, UI, progression, localization, servers and nine different maps.
