- Elite Axe Knight — a tanky elite that storms in every few waves, keeps its distance, and slams a wide shockwave you have to dash through to dodge. A "!" marks where it's entering so you get a heads-up.
- Reward crates — defeating an elite drops a crate. Walk onto it to take one of a random weapon or two upgrades, or sell the whole crate for coins.
- Bleeding — the elite's hits make you bleed for a second, shown by a new bleed icon next to your health bar.
- "Calm" coin pickups — a new pause-menu option that collects coins in place with a soft flash instead of having them streak across the screen, so you can stay focused on dodging.
- Elite numbers ramp up after every boss wave (up to three at once) — but a whole group now leaves only a single crate.
- Elites are invincible for a few seconds as they enter, so they can't be picked off before they reach the arena.
