Grenade: buy one in the Weapon shop, next to the barricade, and carry one at a time. Hold V to aim: a marker creeps outwards from you, release V to throw (at the longest distance it throws by itself). The blast hurts every enemy around the landing spot, and your teammates too when friendly fire is on. Every class can use it, and bots buy and throw them as well.
Skillbooks: three books in the XP shop, Strength, Agility and Wisdom. Each one gives several small permanent boosts for the rest of the run, you can buy as many as you like, and every purchase of the same book costs 50 gold more than the last. Strength: max health, damage, bleed-out time and crit chance. Agility: fire rate, move speed, stamina and a faster revive. Wisdom: XP gain, gold gain, reload time, repair speed and cheaper shops.
Harpy: a new flying enemy, as fast and as strong as the werewolf. It flies over barricades and water, but goes around rocks and shops. It shows up in waves and in patrols from wave 4.
Wyvern: on every 10th wave the first boss is a flying Wyvern with twice the health of the mini-boss. It stays out of reach, spits slow fireballs you can dodge, and calls down meteors on the players closest to it.
Shrines: three ruined shrines in the wild of every map, a temple in Forest and Jungle and a graveyard in Swamp and Underworld. They glow violet at night and show on the map and the Setup map as a dark green flame.
Demon Lord: every 5th wave a Demon Lord with 6 to 10 guards wakes at one of the shrines. Once you wake them they never go back and march on the Core when they lose you. The Demon Lord fights with its sword, spits slow green fireballs at anyone out of reach, and drops enemies from the sky beside the players closest to it. The shrine of a living Demon Lord is red on the map.
Shrines setting: a new Shrines button in the Setup settings turns the shrines and the Demon Lord on or off.
Reload ring: a ring around the crosshair shows your reload. Press R or click the left mouse button at the white marker for a perfect reload (a click does not fire a shot).
Boombox: it wiggles to the beat while it plays. It can be repaired with the hammer, but once it is destroyed it stays gone until the next run.
Mouse: the mouse can no longer wander further than the crosshair, hold Alt to move it freely. While a level-up perk is waiting you see the arrow cursor and can still shoot. Turning the view with the right mouse button works as before.
Controls panel: it shows while you hold Tab.
Engineer: his turrets are now simply stronger (his old bonus is built in), and he can use the minigun and the bazooka.
Minigun: the heating bar floats higher so it no longer covers your character.
Boss health bars: they show only once a boss has taken damage, like every other enemy.
Boombox: a new black and grey model, and the rubber duck is gone from the game.
Setup settings: Gate turrets is now Core towers, Destructible turrets is Destructible towers, Enemy deployment is Enemy patrols and Spawn portals is Wild portals. The text beside each of these buttons says On or Off, and Base shape shows only Square or Ring.
Ground plants: the grass and bushes on the ground come from the same Nature Biomes packs as the trees.
Not being able to shoot or switch weapons with Ctrl and the mouse wheel: the invisible mouse could drift over a panel. It now stays with the crosshair.
Main menu freeze: changing the seed, biome or number of players in the menu no longer freezes the game for about two seconds.
