ADDED

- A boss for every map. Each one has its own look, roar, music and moves, and they come on the same boss waves as before. Every move is telegraphed, and your walls block most of them.

- Gravewood: The Gravelord. Bone spikes burst up in a line towards you, wailing souls drift after you, and its roar raises skeletons.

- The Rail Yard: The Yardmaster. Glowing circles under you, then the ground erupts in fire and keeps burning. It throws three rail spikes at once, and its roar brings brutes with the runners.

- The Bridge: The Stormbringer. Lightning strikes the circles it marks, a wall of water sweeps down the deck and knocks you back, and its roar calls runners out of the rain.

- The Block keeps the Abomination. Every boss gets its own "DOWN" banner when it falls.

- 28 achievements that unlock on your s&box profile. Each one pays 100 to 1,000 coins into your bank (harder ones pay more), with a banner when you earn it.

- Shop → WEAPONS: 4 new weapons.

- Buzzsaw (Frags, Cool, 400 coins): throws a spinning blade out and back, slicing every zombie it passes both ways.

- Wrecking Ball (Rockets, Rad, 800 coins): a huge iron ball that rolls through the crowd, then bursts.

- Ion Laser (Arc Rifle, Wicked, 1,400 coins): a cannon that shoots beam as you charge it up, upgrades to a tri-beam in game.

- Tesla Coil (Tripwire Mine, Savage, 2,200 coins): plant a coil that zaps up to 3 nearby zombies every second for 18 seconds.

- Signature upgrades: a fourth row of upgrades at the top of the streak, a different one for every weapon, Shop weapons included.

- Shop → WEAPON SKINS: 70 skins for the Shop weapons, five each, in a new SHOP WEAPONS section.

- The Bridge is longer and in the middle of a thunderstorm: rain, puddles, lightning that lights up the whole deck, thunder, and new map art.

- A see-through lock over locked maps, weapons and skins.

- Power-ups show on the minimap with their own symbol (a bolt for Adrenaline, a heart for Max Health, a runner for Speed Boots and so on).

- Menu buttons have their own sounds.

- Every Shop weapon has its own sounds now.

- Tesla Coil: a loud crackling zap, a hum while it's running, and a fizzle with sparks when it runs out.

- Buzzsaw: a whirring blade in flight, a bite on every zombie it cuts, and a clink when you catch it.

- Wrecking Ball: a cannon boom, a rolling rumble, and a crunch for every zombie it flattens.

- Prism Laser: a bright zing, plus a glassy ping and sparks every time it bounces.

- Flamethrower roar, Cryo Sprayer hiss, Flare Gun thoomp, Scrap Cannon clatter, Storm Caller thunder, a Minigun motor that spins up and down, a Black Hole drone in flight, and a shattering bottle for Firebombs.

- Zombies catching fire or freezing over make a sound.

- Boss attacks have their own sounds: bone spikes cracking out of the ground, souls bursting, rail spikes clanging, and the Stormbringer's wave roaring and crashing into walls. Each boss roars in its own voice.

- Adrenaline, Speed Boots, Max Health and Armor each have their own pickup sound, and Double Points and Frost chime when they run out.

Two new maps, unlocked with coins:

Gravewood (1,200): an overgrown cemetery. Crypts burst open mid-wave, the dead rise from open graves, the chapel bell tolls every wave, skeletons from wave 3 and mummies from wave 5, and headstones you can shoot over

The Rail Yard (2,000): a freight yard where the night train tears through every minute or so. Get off the tracks, or lure the horde in front of it. Explosive fuel barrels are put back every wave

Map picker on the title screen, plus map choice on Play Solo, Host Co-op and in the lobby

Separate leaderboards for each map

The Shop: spend banked coins on maps and weapon skins
