Escape the city

You have found yourself woken up in a dark tunnel.
What happened, where are you?

Welcome to the Borderlands.

The only way to get out of this is to play the game.!

You will see 3 doors in the tunnel, but you will need a card to activate the doors.
Find the cards to activate the doors and complete the level to go the next one.

But be aware, you are not alone in there.
The city is crawling with guards, who are heavily armed.!
