I would like you to consider to add in sniper rifles, light machine guns, heavy machine guns, assualt rifles, a secondary, and a bazooka. Some helpful iteams like defibulator and health pack, also classes such as medic, enginer, scout, and recon. I would also like you to consider adding vehicles such as a jeep, tank, airplanes, and boats. To get the tank and jeep u would need to get a 5 kill streak for the jeep and a 12 killstreak for the tank they would be airdrops.
Also people dont want to make stairs all the time and can sometimes not see in the dark. So i suggest u add in torches and latters to help them in their conquest for the intel. Also 2 new gamemodes such as, conquest where u capture flags to spawn at one of those bases if ur team runs out of flags then u lose when everybody dies becuase u cant spawn and team death match to just kill eachother to the target score.
