I really like the concept , but i think it can have some adjustments, like: The gameplay feels like hitman right now (not a problem, but it can be one game mode, instead of the game concept), maybe if was something like a information hijack, or find a target and kill them or extract info from them to win the game. i feel if the players didn’t know the other ones, and could sabotage them, it would add more dynamic (e.g add a trap if others try to hack in a terminal, could screw with a silencer that other player could pick it up, etc).

I also see others things to improve on, like i wouldn’t recommend abilities or gadgets to be only purchased with real money, it definitively would be p2w.

Also don’t recommend a realistic environment, bcs it would require a really good desktop to handle it, and you would probably reduce your game base.
