CO-OP CHAT: press T to chat in the lobby and all through a co-op run, ENTER to send, ESC to close. Names show in each player's seat colour, and the lobby posts when someone joins, leaves or is removed
While the chat box is open your keys type instead of play: no moving, dashing or shop / level up hotkeys
A new loading screen: the MASH AND SLASH logo slams onto the lava, the cracks glow, a glint runs along the slash, and a loading bar with your character running along it, plus a gameplay tip. Click, ESC or SPACE skips it
The spuds in the co-op lobby seats now idle and blink, and hop when they're READY
The Broodmother is harder: she pounces from phase 1, pounces twice in a row in phase 3 (the second leap re-aims at you), chases every web sling with a stream of aimed silk, darts and attacks faster, lays more egg sacs (up to 10 spiderlings), and her web balls fly faster
Broodmother Silk Rain: the globs fall faster and in the second half one also lands where you're heading, with more spits and denser silk curtains
Broodmother Spinning Web: 4 threads instead of 3, and she attacks faster while she spins
The War Mech is harder: it attacks more often, walks faster and keeps closer, its minigun fires faster with quicker bullets and ends in a shell blast from phase 1, rocket swarms are 6 / 8 / 10 rockets (was 4 / 6 / 8), and missile salvos have more crosshairs
War Mech phase 3: the minigun opens up straight after a rocket swarm
War Mech Carpet Bomb: the bomb patterns come faster, and the aimed minigun bursts run the whole phase instead of just the second half
Both bosses hit a little harder (about 10% to 15%). Every new attack can still be dodged on foot or with one dash
The tutorial cards show your own character and the new enemy art (and follow the CLASSIC art options)
Run details: every section keeps its size on long runs, only the upgrade list scrolls, BACK is always on screen, and runs over an hour show the hours (1:34:58 instead of 94:58)
Co-op: everyone needs V0.94 to play together (older versions can't join a V0.94 lobby)
The Broodmother and the War Mech are bosses 4 and 5 of Boss Rush, so the changes apply there too
Co-op runs still don't count toward your best wave, leaderboards, mastery, daily missions or achievements
Co-op (and its chat) hasn't had a big online test yet, so expect some rough edges
You can't join a co-op run that has already started, and if the host leaves the game ends for everyone
In co-op the Carpet Bomb's safe block can still appear anywhere, since one block can't be near every player
The tutorial's King Slime still uses the classic slime art
Weapon fire rate is very slightly tied to frame rate
The Elite Hunter achievement description on the achievements page may still show the old text
