Are you a sucker for __pun__ishment?
Can you think of a Christmas-time/holiday themed gametype?
Can you rename an ability/weapon for holiday use?
… Care to try a slight variant on new and old classics?
Disgruntled Elves
Mini-Slayer, er petite-elf slayer.
Automatic Icicle Spewers (SR’s) and Green Gelatine Globers (PP’s) with Ornament Bomb (Pulse) starts. The SR and PP could stand to have their own damage increase. A 25% more damaging SR and 3-health shots for the PP to kill.
PoD’s are littered with Xmas-themed weapons such as the Blade of Ice, the Abominable Snowman’s Mallet, the Light of Rudolf, etc. Powerups and abilities include but not limited to are Santa’s Strength, Jack’s Speed Frost, Grace of Aurora Borealis, Santa’s Naughty Vision and Aegis Frost Shield.
Olive vs
Smashing Punkins variant, ie FFA Oddball variant. More festive forced colouring for the “reindeer” and Olive holding the ball would of course be nice 
Concussion Rifle and Scattershot starts… I mean Rudolf nose projectiles and tinsel-shooters for all. Stickies, I mean snowbombs off spawn.
Slightly increased jump height and speed, plus Jetpacks for all. Except being reindeer, gravity is slightly less influential.
The increased base movement speed, low gravity and jetpacks should make CR kills a bit more chaotic. Getting in too close gets a face full of tinsel
Reigndeer Games
Santacide! And everyone wants to be Santa.
It’s Santa’s Incineration Chimney Cannon and Naughty Vision vs the reindeer’s quicker cooling “Light of Rudolf” pointers. As well, Santa get’s ornament bombs, the reindeer get snowbombs.
Reindeer are slightly floaty with jetpacks, Santa gets to run slightly faster and jump slightly higher than the deer due to their flying ability and numbers.
