So me and my friends want to make our own custom bf2 server and we also wanted to jank around modding the thing

and we thought wouldnt it be fun to make our custom kits in the sense that in game we can like chose to have medic packs and ammo packs and we can choose every gun with every class

is there any possibility that it might work modding the game or should we put us out of our head

we dont mind having to make ungodly sacrifces to make it work

Have you seen https://www.moddb.com/games/battlefield-2/mods ??
There are so many mods out there and with the weapons unlocker every class can use every weapon already!
Btw, Medic- and Ammopack can not be used in one class, i mean i never saw it before. Actually a good Idea.
