Here it says: https://robertsspaceindustries.com/comm-link/Comm-links/19735-Arena-Commander-Modes-Schedule A player must participate, until match completion, in every Experimental Mode during this patch cycle. Note that leaving the match before the post-game scoreboard appears will not count towards the badge. Modes include: Tank Royale Team Tank Battle Single Weapon Elimination Master Modes: Squadron Battle (Replaced Master Modes: Duel) Master Modes: Classic Race Master Modes: Endless Vanduul Swarm Kill Collector (FPS) Kill Collector (Vehicles) Duo Showdown Team Elimination So i guess i need to participate in ALL of them but my questions are: Duo Showdown -> is this Duel starting 21 Jan? Kill Collector (FPS) - What is this? Kill Collector (Vehicles) - What is this?
