Just as Reggles said mutipliers will need to be removed, after we become compliant and things ease up we could possibly re add them in a way the benefits everyone.
On the shop for $5 purchase the 2x booster for [selected minigame] duration 30 minutes. All players playing that mini game will be boosted the same amount no matter what rank they are.
Have a rotation every 2 weeks a certain minigame will have a 1.5x boost: 1st Infected, next fortnight Halo, next fortnight Boomo, next fortnight CTF and repeat.
Possibly when the server reaches x amount of purchases in a month there is a random minigame booster that lasts a few hours.
These are just some suggestions, nothing staff 100% plan to do at this given time.
