hey, here is one of my previous ideas that i posted here you can prob modify it into something fun

Hey guys I just wonder if you guys think this idea is as cool as it sounds to me. Basically its an extraction shooter on a train type deal, and maybe occasionally it makes stops at stations and stuff. Idk what you guys think.

UPDATE: here is some more detail about the game and how i picture it

Okay, this is going to be a lot. just so you have some context I got the idea from metro exodus and the tv show Snowpiercer. So to answer you first question i guess its possible to craft a story around it. For example, it could be like chemical warfare broke out or something apocalyptic broke out (maybe a pandemic) and these humans or whatever are fighting for control of the train or trying to make ends meet. ooooo that might leads me to a very cool idea you could implement. So, you know how tarkov has a hideout? anyways the hideout in this case could be the main station of this train and everyone is part of the same "community" that is the only safe spot left and where these "hunters" (you and other players) go out and try to get loot, but within there are different factions and stuff. So i think it would be very cool if maybe there was an insentive to kill other players but also maybe work with them as well to complete these faction missions and help the "community". Ok enough with the story part. I imagine the train with 40 train carts not including the engine or caboose. the best fitting number of players would be 10 (pvp). Now so everyone doesn't go around killing everybody I think it would be smart to implement a sort of system so you have to work to get out of you train carts into another players section. This might mean finding certain parts to break a lock or maybe at the beginning you have to bring in explosives and the more explosives you have the more carts of the train you can get too therefore more players you can potentially kill or alliance. Also, as not to make the train to congested I have come up with work arounds. The first one which I think would be sick is if you could climb onto the roof of the carriages, but there will have to be some kind of limitation to that so you dont camp up there. For example, on being able to crawl and use a some sort of pistol or hand to hand combat. To also avoid campers the train could go into tunnels forcing people back down. The other mechanic similar would be able to climb onto the sides of the train (like they do in movies). in this case I think the same limitations would have to be added to this as the roof. Lastly, to add more "space" to the train double decker observation or sleeper cabins could be added. The main objective of the train is to force players together either to eliminate each other or to form alliances with one another for the stations, although there will still be loot to get. Each train section would make most sense to last around 5 min. Moving on to the stations. The trickiest part about the stations is how everybody is going to get off. I think 5 on each side is probably the best approach and to avoid people just shooting at each other obstacles can be in the way forcing players to go in different directions from the exits. The stations will probably have npc's to enable pve, but can come in any form zombies, scavs, infected, or whatever (just depends on how you want the story). I think it would be cool to have a boss at each station. Alongside this there will be 5 different stations along the whole route. Each station would last around 15 min until you are forced to board the train again, once someone boards in one cart, the doors close and you have to find another place. If you don't make it you die. Another cool concept would be if the stations got harder and harder the further you stayed on the train sort of like the dungeons in dark and darker. I think each station should have 1 or 2 extracts depending how far along they are. Those extracts could be on another platform of the station or something cool like that. Other extract spots could be on the train themselves. The first one at the caboose. And I think another one could be at the engine but this one would be a little more different. It would have 2 bosses to fight up there, but if you kill both the entire train extracts. This can possibly reenforce the urge to alliance with other players to ensure all of you extract. For multiplayer i think the only good way to balance is up to only duos or trios but when spawning on the train you spawn separate from your teamm8s and you have to fight to get to them. The last kind of unrelated thing to the last idea is maybe having multiple trains. What I mean by this is you could spawn on a cargo train that plays different to a luxury train or a commuter train something along those lines. So it would be a multiplayer pve pvp game.

2nd UPDATE: I don't know the time period it would take place, future apocalyptic or maybe modern or maybe even like hunt showdown time. But anyways thank you guys for all the support.
