How to make it so you have to collect a few items to let you progress the level?

So basically I want to make it where you have to find 3 key cards in the level.. Once you get the third key card the level ends and it goes to the next area.. Is there any easy way to do this>?

Could make the last card an exit branch entity. Assuming you collect the cards in order.
Else scripting would be needed

Tricky! I never thought about to turn an item into a boss.
