BlockGunner

Blockgunner puts its choices in plain numbers: three maps and three weapons for a two-player fight. The source describes an HTML5 war game meant for playing with friends, with victory in the confrontation as the broad aim. It does not identify a separate campaign or a solo opponent.

The short description leaves the finer rules open. There is no stated hit count, round duration or explanation of weapon differences, and no confirmed upgrade economy. Those are useful things to inspect in the match setup rather than inventing a standard shooter format just because the game includes guns and multiple arenas. Blockgunner supplies WASD with R, arrow keys with O and mobile touch controls. It does not attach named actions to R or O, so use the in-game control display before assuming which button attacks or changes equipment on either side.

Begin by learning one map's space and one weapon's response. That gives you a clear comparison when you try another choice, while checking both players' action keys keeps the first duel focused on the game instead of a missing control explanation.
