Barrels Up is a classic shoot ‘em up game that is set in the Wild West. Players are charged with defending their dusty and rather deserted town by shooting barrels to detonate them before they hit the various buildings and kill the townsfolk inside and there are plenty of different weapons to select to get the job done. However, anyone who wants to be able to join in the fun should note that they will need to purchase a Windows Mixed Reality immersive headset first.
