Here is my list of idea that I think would benefit this game; Let me know if you have any further additions or grievances!
1: Some sort of “Perk” system. Say have tons of perks (Unlockable, obviously) that would help benefit the player. They need to be made in a way that it doesn’t necessarily give 1 perk and edge over another. Some ideas could be “5% increase with the shotgun” or “10% chance to dodge explosions”
2: Definitely needs some sort of chat system; Both in-game and out of game. This certainly seems like the type of game where trash-talk would be acceptable.
3: Friending system. Have a way for friends to join matches together
4: Please don’t make any Kred-only items. If you must, make them extremely expensive but don’t make them cred-only. That ruins the game.
5: Make it permissible to permanently own an item with in-game money.
6: Going TF2 style here but… HATS!
