A zombie wave gameplay like in all decent fps games? (shouldn't be hard since the AI on arcade have their own self-act already done)
Implement weapons created by the community 1 time every 3 months? (so people could learn modeling on maya) Or even skins-only are gud
Add new phisiques like breaking the ground? Improved walljump to get the feel of being really on s4?
Try to find a perfect balance between shop and pen-users,so those that donate towards the server will not have that huge advantage. I honestly prefer that you give to donators unique skills or skins/set instead of tremendous advantage over other players
Maan,there's literally a ton of things that i would like to be realized on this game,because s4 was such a unique game on it's own before it has been transformed into a "milking the cow" machine
