20 new arenas built around something big that moves, 9 new weapons and items, stopped time, one-click game modes and a long list of fixes. Here is everything that has changed since the trailer.
Windmill Hill – Forest: ride the windmill's turning sails across the gap
Turnstile – Comic: a giant turnstile snaps a quarter turn and flings whoever is on it
Morning Star – Volcano: a huge spiked flail whirls over a lava lake
Wrecking Crew – Rooftops: a wrecking ball swings across the rooftops at head height
Clock Tower – Rooftops: ride the clock's pendulum between two far-apart rooftops
The Great Wheel – Blueprint: hop into a Ferris wheel car and ride it over the pit
Assembly Line – Blueprint: conveyor belts carry you to the edges and keep reversing
Rubber Stamp – Desk: three giant rubber stamps slam down one after another
High Seas – Harbor: a ship rolls on the waves and everyone slides towards the sea
Boulder Dash – Volcano: a boulder rolls from wall to wall, so jump it or get up high
Block Party – Notebook: blocks drop out of the sky, squash whoever is under them, then stay as platforms
Orbital Ring – Space: platforms orbit a space station on two rings in low gravity
Teeter Totter – Chalkboard: land hard on one end of the ruler to launch whoever is on the other
Timber! – Forest: tip the tree with weight, punches or a hard landing and it flattens anyone underneath
Rickety Bridge – Harbor: every plank gives way a moment after you stand on it
Lantern Swing – Dojo: paper lanterns over a koi pond to stand on, swing and knock together
Tip the Scales – Chalkboard: a giant balance over spikes where the side with more people sinks
Pushpin Panic – Notebook: sticky notes pinned through the middle spin if you stand off-centre
Heavy Bags – Comic: hit the punching bags hard enough and they swing back and flatten someone
Domino Rally – Desk: push one giant domino over and the rest follow, flattening anyone in the way
Deagle – a hand cannon: 38 damage, dead accurate when fired slowly, sprays when spammed
Cyber Katana – every swing knocks bullets, rockets, arrows and thrown weapons back along your aim
Flail – a spiked ball on a real swinging chain with huge reach and knockback
Crossbow – a fast, flat bolt for 80 damage
Kar98k – a bolt-action rifle: 100 damage, and you work the bolt between shots
Gold God Gun – fires one golden God shell that explodes on impact, but if its own shell or blast hits you, the gun is gone
Time Gun – freezes whoever it hits in a bubble of stopped time for 3 seconds
Time Grenade – a ticking pocket watch that bursts into five bubbles of stopped time
Extra Life – a heart pickup that gives you one more life this round, whatever you're holding
Time bubbles – fighters, bodies, rockets, grenades, arrows and loose weapons freeze inside and carry on when time starts again
Frozen hits – hits on a frozen fighter still count, and all the knockback lands at once when time restarts
Prone block – raise your guard while lying down, deflects included
Low jab – attack bare-handed while lying flat to hit fighters who are down too
Shotgun pogo – shoot at the floor to bounce yourself up
Crushing – a falling tree, domino, dropped block or stamp that pins you is lethal
Game mode presets – Normal, Chaos, Slow mode, Fast mode, Big boy, Small boy and Fun mode, each with its own weapon settings
Unselect all – switch every weapon off in the weapon list, then pick the ones you want, and none at all means fists only
That's you aura – your fighter burns with a super-power aura in your colour during the countdown and the first 5 seconds
Locker live preview – your stick figure shows off what you've picked, and hovering any item tries it on
Pickup tips – picking up a weapon shows a line about what it does
Corner blasts – falling out of a corner of the screen fires a diagonal blast from that corner
Rate the game – a button on the title screen and Esc menu that opens the game's page to like, favourite and review it
Suggest an idea – send ideas, bugs and weapon or map requests straight to the developer from the title screen or Esc menu
Melee reach – punches, kicks and melee weapons reach exactly as far as they look and scale with player size
Rockets – a direct hit explodes on the target for the full 100 damage
Minigun – bullets are now fat white-hot slugs racing down the tracer
Teleport Gun – blinks you through one-way and thin platforms and lands you on top
Gold God Gun – now fires a single explosive God shell instead of a laser, with a deep cannon boom
Weapon and map lists – fit all 39 weapons and items and all 50 maps
Health bars – show your HP number, with splits that follow the lobby's max health
Difficulty – easy bots aim wide and react slowly, while hard bots aim true, guard, dodge rockets, lead moving targets and go prone under fire
New tricks – bots grab Extra Lives, swing the Cyber Katana at incoming fire, and ride and avoid the moving parts on the physics arenas
Point-blank rockets – no longer fly through the person you're aiming at
Rocket self-kills – your own rocket can't kill you if it hit someone else first
Picking up weapons – weapons now fire straight away instead of waiting out the punch timer
Add and Remove bot – the buttons did nothing because auto-fill put the bots straight back
Winning bots – no longer jump off the map between rounds
Fallen tree – bodies were split in half under it instead of being crushed
Outlines – no longer drift off moving objects on the physics arenas
Station ceiling – with the Low Gravity twist or a jetpack you can end up on top of Station's ceiling, out of view, and the edge arrow shows where you are
Moving platforms – on Scribble Pit and Crane, bots only ride a platform across the gap when one is close, otherwise they wait or take the high route
Laggy overlaps – with a lot of lag, two fighters' bodies can overlap for a moment
