High Noon

From BoardGameGeek:

Howdy, partner! In High Noon, players control different posses vying for dominance at the turn of the 20th Century in the fictional Wild West state of Saratoga. Players send their posses into battle to settle their scores the only way they know how: gunslinging. Loot crates are strategically placed across the board and have the ability to give each posse a unique advantage during the firefight. Within the loot crates, players will find valuable supplies, medicines, and firepower to give them an edge against their opponents. Victory is declared at the end of twelve rounds at which time the posse that has collected the most gold wins. Gold is awarded by how much damage and mayhem is dealt in the shootout. Alternatively, players can continue the fight until one posse remains and is declared the "Last Posse Standing".
