Revenge - the snake that ate you is marked with a red arrow after you respawn

Payback - eat them back for +50 coins on top of the usual kill reward

Stolen revenge - if someone else eats your target first, your revenge moves to them

Four bosses - the boss is now one of four, and the same one never comes twice in a row

Devourer - hunts the nearest head

Frost Wyrm - freezes every snake near its head every 5 seconds

Magnet Wyrm - pulls food into its jaws, so the best loot piles up right in front of the deadliest head

Splitter - drops ÷2 signs behind its tail, so cutting it is a gamble

Boss hint - a line under the boss bar tells you what this boss does

Payback - a new achievement for taking revenge
