Destiny and Overwatch don't have a lock on over-the-top holiday gaming modes. Gears of War 4 just got a 99-cent Gearsmas Pack that adds some cheer to a mostly grim and dark game. The centerpiece is a special multiplayer event, Snowball Fight, where you have to fling snowballs at rivals using a custom Snowshot weapon. Akin to a real fight, you can't just reload -- you have to scoop up more snow ammo once you've run out of what little you have. There are also three ugly sweater-clad characters (JD, Kait and a Swarm Drone) and 24 holiday-themed weapon skins. Gearsmas lasts until January 4th, so you'll want to act soon if you're going to show off.
