How to access the last act

[Skull]

Can someone tell me? I not rly a big fan of figuring these kind of things out...

1. Win the game as Ironclad, Silent, and Defect (at least once for each character)

2. When you play the game after that, you need to collect 3 keys to go to Act 4

Red key - get it at a campfire
Green key - kill a "stronger" elite (on the map, it is shown as a elite on fire)
Blue key - give up a relic (when you open a chest, a blue key will be connected to a relic. Click the blue key)

You don't have to get all 3 keys in one Act, but you'll need to get them before ending the game in Act 3.

3. After you defeat Act 3 boss, you'll be able to access Act 4
