Sticks, Stones & Laser Guns

In Sticks, Stones & Laser Guns, the objective is for a duo of players to take down entities spawned by a time wizard. Said time wizard scrambled two groups of humans in their timelines, sending a group of late-Paleolithic hunter gatherers into the distant future and a group of cowboys to the medieval ages. Those two groups come together to take down their powerful common enemy, using whatever tools they found in their displaced timelines to fight back against the powerful entities.
