Brawl Gun

Three maps and three weapons form the stated fighting selection in Brawl Gun. The description calls it a two-player war game for friends, with nine costumes and nine ranks also listed. That gives the duel several confirmed choices without assuming a larger campaign or a particular online setup.

The source does not explain how ranks are earned, whether costumes need unlocking or what distinguishes each weapon. It also leaves the score target unstated. Choose equipment from the game itself and learn its behaviour during a match, rather than treating the number of options as evidence of particular damage values or abilities.

Brawl Gun lists WASD with R and the arrow keys with O, plus mobile touch controls. The instruction field does not label the actions attached to R and O, so check the in-game guide before calling either key fire, reload or weapon change. Try one weapon long enough to notice how it fits the current map. A different arena may favour a different approach, and confirming the action buttons before the duel gives both friends a fair starting point for learning those differences. You can also challenge a friend to a shooting duel in Gun and Guys.
