Is WARDOGS a battle royale or an extraction shooter?
Neither. WARDOGS is an objective-based control-point shooter. Three teams of up to 100 players total fight over a randomised 2x2 km Control Zone, and the first team to 100 points wins. There is no shrinking circle and no extraction.
Neither, and the distinction matters if you are deciding whether to care about it.
There is no shrinking circle and nothing to extract. Three teams fight over a randomised 2 × 2 km Control Zone and the first to 100 points wins the match. You respawn, you buy a new loadout, you go again — the pressure comes from holding ground, not from a timer squeezing you into a smaller map.
The closest reference point is King of the Hill, the Arma 3 community mode Bulkhead has openly cited as the inspiration.
