There's so much that you can do on a casino setting
Setting new mechanics based around gambling points and getting new rewards like:
-Playable slot machines
-Blackjack
-Poker
-Roulette
And the list goes on and on and on
I also feel like it would be appropiate if the map had a celebrity cast and hiring actors that made popular heist movies like:
– Vincent Cassel (From Ocean Eleven)
– Jim Sturgess (from 21 Blackjack)
– Eiza Gonzales (From Baby Driver)
– Jason Statham (From Snatch)
Just to name a few and i didnt choose the most popular actors because realistically celebrity cast maps didn't had the most popular actors but also are well known
The easter egg could play like a heist, like stealing a secret document or artifact that its important to the overall aether story and with steps that feel like a true heist.
Let me know waht you think about this idea but i feel this could be a fun map to play kinda similar to Zombies in Spaceland with the arcade machines and games playing a similar role to the mechanics of the playing games in the casino
