Classic 59 - Back to 2016


Remember the old-school Mitosis? Classic 59 brings it back as a new mode, with the physics of 2016 and the original rules, stats, caps and items.It has its own equipment bar, with your pet in slot 4 and no gem. Look for the 59 READY seal: more than 300 classic equipment pieces, pets and potions are back in the shop.You'll also find ONLY 59 potions with the classic powers: Speed, Gravity, Blink, Shields, Portal Guns, Chainsaws, Power Splits, Glue Launcher, Red Virus Seed and more.Open the shop from a Classic 59 equipment slot to see compatible items. You can play with up to 2 accounts per player, and your quests, achievements and EXP still count.Look for the 59 seal in the mode selector. The latest game version is required.

Survival Powers - Make every minute count


Staying alive now gives you more than a bigger cell.A new survival bar tracks your time alive and unlocks 8 powers over the course of each life. Passive powers stay active once unlocked; active powers can be used once per life. Survive long enough, and you'll reach your Ultimate.

  • 0:30 - Nimble: your cells move 5% faster.

  • 1:00 - Quick Rejoin: rejoin 10% sooner.

  • 2:00 - Metabolism: gain 10% more mass from food.

  • 3:00 - Sprint: gain 50% speed for 4 seconds.

Guild wars, tournaments, 1v1 and 2v2 keep their existing rules.Worm.is gets its own progression too: Nimble, Efficient Boost, Digestion, Free Turbo, Deadly Molt, Blade, Hydra and the Leviathan Ultimate.

Proximity Voice Chat - Hear the arena


That player next to you? You can talk to them now.Voice chat works across PC, Mac, iPhone, iPad and Android. Players on your screen are at full volume, and their voices fade as they move away. In team modes, you always hear your teammates and never the opposing team.Use push-to-talk with V on PC, the mic button on mobile, or voice activation with noise filtering. A speech bubble shows who's speaking, and you can mute individual players.

Match Replays - Watch that again


A close escape, a perfect split, a chaotic finish: replays capture the last 5 minutes of a match, including the map, leaderboard, chat, powers and effects.To watch a replay, open Settings > Watch Replay and enter its code.Scrub through the timeline, watch at 1x, 2x or 3x speed, follow a player or explore with the free camera.

Free Tournaments - Bigger prizes, no tickets


Tournament entry is now free.There are 3 tournaments every day in each zone - Party, Hardcore and Ghost - at rotating times, with these coin prizes:

  • 1st: 10,000 coins

  • 2nd: 5,000 coins

  • 3rd: 2,500 coins

  • 4th–10th: 500 coins each


The gem slot is disabled in tournaments. Check the countdown on the home screen and watch for announcements in chat.Grand Tournament: every Saturday, Battle Pass Premium players can compete for special top-three prizes, multiplied ranking points and an exclusive title for the winner.

Direct Guild Wars - Straight into the fight


Jump into guild wars without waiting for matchmaking. If your team is outnumbered, an ally joins the fight wearing your guild's colours.Every win awards 80,000 EXP. Every 3 wins also earn you 600 coins and 600 Gem EXP. Your victories count towards your profile, the guild war leaderboard and the season.

Gem Training - Progress while you're away


Put your gems into training to earn EXP every hour, even while you're offline.There's a new training screen, quests now award Gem EXP too, and the gem shop has a new daily Reroll.

Ghost Solo - Halloween until November 9


Ghosts have taken over Solo!Everyone starts as an anonymous little ghost with a spooky name. Grow beyond 300 mass and you'll turn back into a cell wearing a surprise Halloween skin.There's also a Ghost tournament every day. Jump in before November 9 and haunt the arena.

Living Cells - Every split feels different


Your cells now stretch before they split, melt together as they rejoin, squish on contact and pull in their prey.Movement between your own cells is smoother too, with the jittering removed. It's a change you'll notice from your very first split.Hold TAB to open the new live match leaderboard and check every player's mass, highest mass, time, cells eaten and kills. On mobile, tap the leaderboard.
