Hey there Billies! "Jolly Edition" seasonal content is now active in TWBI. For the most part the changes are aesthetic (a new addition may change that in the coming weeks). Feel free to fire up the game and discover things for yourself (ensure that Seasonal Content is set to "auto" on the Options page), or check out the list of changes below:

• All bullets are replaced with snowballs
• Dust clouds are white
• Red ink (ie 'blood') is replaced with white ink (ie 'snow'!)
• Helmets are replaced with Santa hats
• Smoke is red, white, or green
• Rockets leave behind glitter instead of smoke
• Grenades explode into glitter instead of fire
• Rainy weather is replaced by snow
• Some aesthetic changes to main menu

It's time to get jolly*!

*or not; you can disable seasonal content on the game options page. Humbug.
