Endless waves with random modifiers.

- 3rd and 7th wave: Challenges

- 5th wave: bonus (collect team lifes)

- 10th wave: bosses

- complete random challenges to level your teams armor, health or damage (+5% for one attribute which is random)

- on every wave (despite bonus or boss wave) there is a chance of 10% that an elite demon will spawn (if you kill him you get +5% on armor, health or damage)

- you can sacrifice a team life to increase all 3 attributes +5% (life converter)

- each demon drops an orb and you need 20 orbs to unlock 4x team damage each time

- there are secrets which unlock a music box, team haste x5, team berserk x3, extra team lifes and mega heal spawns

- SPECIAL: beat the high scores to enter a top 5 solo leader board and the elite demon can spawn with your name (random) as long as you are in the top 5 leaderboard (permanently added to map and will update from time to time)
