I believe that it would be essential it include an item shop for the Personoids that would spice up gameplay. It could appear as a dispenser/vending machine (As Troels Nygaard said in my last post) and should be placed in risky locations to make it a gamble to buy something. Personoids should be allotted say 3 tokens at the start of the round, and there are gadgets that should cost 1/2/3 tokens depending on the power of that gadget. Personoids should be able to do tasks, such as "Inject one resident" or "Survive two keycard insertions" or "Sabotage three oxygen stations" to get another token. Some items that could be included are the scanner spoof item I made another post about, maybe a one time disguise that gives you another players name tag and appearance, a log locater (To sabotage easier), and if you're daring, another syringe. You could also put some common items in such as the sprint burst, racket, and so on. I believe this is an amazing addition, and would improve the replay-ability and dynamic situations of every round!
maybe not using token, but using your pesonoid shorcut key instead, and making the item drop random, that would be a true gamble :)
it would be really cool, but maybe too OP since the Personoids already have the power of deception at their desposal.
