System Shock Map - Collecting Ideas

I'm planning on making a System Shock type of map. I have lots of ideas for it, but can't really incorporate all of them in one map. Should I make it a single- or multiplayer map? Should it be a survival or more of a RPG style? I need your input, people. Give me your opinions and suggestions so I can make the best of this.

System Shock

A map with a sort of System Shock 2 feel. Player(s) must try to survive in a spacecraft infested with all sorts of dangerous organisms and robots.

Although I have planned a quite complex weapon system as well as many different weapons, I don't want to have too much fighting. If a player wants to try and survive without having to fight anyone, he can. Of course one can just as easily concetrate on getting better equipment and fighting skills, if he wishes, although I think a more balanced approach would get the best results.

this seems to me like an escape the prymid kinda game where u get different things to do but seeing as there is very littl ei can desiper from the description of what it will be like plz make it more in deapth

Well, I guess it could have some resemblance to the Escape map. There are some good ideas I might end up using in it. But right now I'm asking people to give me suggestion whether or not make a multiplayer or singleplayer map. Singleplayer map has couple of obvious advantages: it is much simpler to do and it can be bigger and longer by having multiple maps/areas in it. Some people of course prefer multiplayer. Which one should it be? I myself could be happy with either one.

I'm nearing the end of SS2 right now, and the thread title caught my eye. Will it be based on the SS2 story, another completely different one, or a sequel? Whichever one, it would probably be best not to have any SS2 spoilers in it.

If it's multiplayer, it might get confusing to have a save/load system. I always find those maps are more unbalanced since some players start with hours more experience and stats. Then again, without a save/load system, the game would be very short. I dunno, maybe a short map would be better, but I'm not a fan of loading your character at the start of a map.

What might be VERY interesting is competative multiplayer: perhaps an AI has pitted you all against each other, and whoever reaches the end first is the "avatar" and gets the escape pod or something. With only six inventory slots to hold keycards and stuff with, it would be fun to have to hide items from other players and set up traps for them. If you choose competative, there'd definately be no saving your character.

And as the maker of PE, you can borrow whatever from that map, but I don't really see how it would fit. And one more suggestion: enemies should do a lot of damage, so they can often kill you in a few hits. Players should deal not much damage, but the monsters have lower hit points than players.

I did think a bit about the possible story and came to the conclusion that it shouldn't be the same as System Shock 1-2 had. I might even end up not doing a story at all, even though I will probably make it a singleplayer map. And that load code thingy will not be implemented, it just doesn't fit.

And if you have played System Shock 2 could you tell me what you liked/hated about it? Did you like that fact that nanites were used for almost everything? Or should for example hacking require different "power source"? Is the ability to buy items too silly? Etc.

Right now I'm going to do basically a copy of System Shock 2 with some differences in skills and equipment, but with the same basic things.
