To all haters of the idea or believers that it gonna get raided every ever since its created why not spawning new characters there and once out you would never see the base again, so it would be invisible.
At lvl 5 no NPC would talk to you so simply you wouldnt be able to do anything and on first NPC contact you would be said that you need to empty the locker as it will disappear or you wont acess it after 24hrs.
Ok, so since it wont be visible on the map, there should be some battle training. You need to talk to the NPC and select your weapon skill you want to practice: SG, EW, BG or HtH, youre being spawned to a labyrinth made of brahmin fences with a mauser, flamethrower, laser pistol or sledgehammer/spear and starting from rats, through ants and scorpions youd go through it. I guess there should be NPC telling you what to do next to each "arena" like "make aimed shot" "reload" and so on.
There could be some other ways to achieve xp or try out some Fonline features, like if you have 3CHA youd be able to get the quest in which you and your slave would battle golden gecko.
THere could be a couple of NPC in one place who would give quests like:
>"we will talk once you achieve a skill of 40% science. Remember, once you gain a level press 'C' button and add skill points on the right side of the window that spawns up". Of course youd get a hammer and a mission to mine X minerals and X iron ore. NPC would say "go to the north rocky side of the city and find a big, green mutant there" The Mutant would then explain how to mine "press 'I' and drag your hammer to lower 2 boxes, so called "active slots" press OK and if you dont see a hammer press the red button and your hammer should appear. Next, click with right mouse button until you see "USE ON" next to your hammer and then press left mouse button on the rock left and right to me"
>"Im a repairer, would you like to follow me in this profession?". Youd then try with your current repair skill to repair a thing. Of course, similar explanation should be given as above...
THere are many possibilities, and dont tell me Fonline should be different. Its only fonline Ive never seen any care of starting players.
I dont know about the locker... how big do you think that base would be? I think primarily role of such city would be to get experience not weapons.
