Boss costumes - THE REWRITE with a jack-o'-lantern head, SOON™ as a bat

Skeleton - a costume for you, DRESS on the title screen, for every career rank

Graveyard Shift - a song of its own for the main menu

Joining friends - friends can join your build from the s&box friends list, and picking 2 players at Play hosts one for you

Shared build - one arena, one set of patch notes and commits, level-ups take turns

Daily build - one build for everyone each day, a new one at 00:00 UTC: the same map, release channel, starting weapon, enemy order and boss order

Same patch notes - every wave of the day's build rolls the same patch notes for everyone, and the commit offers come from the same rolls

Daily board - your best run of the day goes on the new DAILY tab of the leaderboards, next to yesterday's board. Retry as often as you like, only your best run counts

Spooky dailies - until Nov 8 the daily builds roll the Spooky Season too, so gm_graveyard can come up and SCOPE CREEP is the first boss

Zombie Processes - they shamble in from wave 3, and killing one isn't enough. It goes down and lies there defunct: shoot the body or dash through it before it gets back up (kill -9), or it rises as a ghost that's faster and floats straight through props

Cursed wave 13 - every 13th wave the build server loses power. The screen goes dark and your aim is the only light, muzzle flashes, explosions, portals and jack-o'-lanterns light things up for a moment, and all you can see of the horde is their eyes. Something in a bedsheet is coming

SCOPE CREEP - a new boss made of feature requests. It starts as an MVP, then it's an MVP + multiplayer, then an MVP + multiplayer + open-world MMO, and it keeps growing for as long as you let it live

Unlabeled commits - a new card in the commit picker with no message and no diff. Trick or treat: a free rare or epic commit, or a regression ships with the next wave

Haunted build - a new patch note: some of the dead come back, some of them in bedsheets

Achievements - 3 new ones: kill -9, Power Restored and Scope Cut

Costumes - some Placeholders come as jack-o'-lanterns or bedsheet ghosts, and T-Posers wear witch hats

gm_graveyard - a new map at night, with a tombstone for everything we shipped: RIP FLASH, RIP CS:S, RIP MY WEEKEND

Pumpkins - jack-o'-lanterns on every map, and SCOPE CREEP is always the first boss

Main menu - dressed up too: a moonlit arena, fog, bats, a spider, cobwebs, a jack-o'-lantern and slime on the logo, and a music box playing somewhere

After Halloween - Zombie Processes, the cursed wave 13, SCOPE CREEP and unlabeled commits stay. Only the costumes and the graveyard go back in the box
