The Sampler Matches have been updated, for this fortnight you can sample the FreezeTag game mode on Grim Dungeons.
FreezeTag is a game of freeze or be frozen. Two teams collect weapons, armor, and powerups, and attempt to frag the opposing team, causing them to freeze in place. Frozen players can be thawed by the heat of their teammates standing close by, or by being pushed into an environmental hazard. Teams score points by freezing the entire other team.
As always, the Sampler servers are available in limited capacity, so look for matches named "FreezeTag Sampler" and enjoy!
