It is concrete multiplayer description for SR2, then, sadly, wasn’t described by others yet.
What should it be? In-game (not mode, because many players don’t check site and also IOS can’t have mods) cross-platform multiplayer with official and custom servers. For multiplayer we also need to add in-game mod list where you can switch on and off mods then you already have and of course button then would sent you to site like at SP. Also in this multiplayer you can only move - no building online (well, you wouldn’t leave server while building or changing spacecraft, but other players couldn’t contact with or look at you).
Public multiplayer. What is it? It is several server types, then are official and requires no mods switched on. This servers are also smaller then single player (but some of this - no) because it have limited players value at the same time, and if it’s world would be too big, players just wouldn’t meet and would play like at single player. As the first server will become ful, will be created next. The value of players at and sizes of server will depend on type of server.
What servers are officials? It are servers then were officially created by developers right at the start of game and can create or remove itselves automatically as the last server is full or this is too empty. It always have sertain place at galaxy, like at certain solar system e.t.c. What modes are this servers?
First mode: sandbox. No guns allowed. Here you can just have free fun. Of course, there would be chat, players list and report button - as at any other official server. Sizes would be 1 solar system for 20-100 (I guess maximal value would be 50) players. Also, if you will get to the border of location, you would just get back like at War Thunder Plane Mode.
Second mode: war. Here we would join to one side of conflict and fight at your craft. All other concrete things would be done by developers - like you can join whenever you want or only at the beginning, e.t.c. Maximal players value - 20-50, sizes of location would become even smaller than at first mode.
Third mode: clans. Ye-Ye, you could join to clan and play at the most big, global mode! What is this mode? Well, it have 2 ways: expansion and war. Personally I would prefer expansion mode, but war mode would be fine too. What is the first one? It is mode with robotic base colonization. If whole clan would work at the same time, they could build planet base and deliver it to the other planet where they could make their one save (then would be impossible without base) for whole clan and use this base for launching of rockets, and this rockets would fly farer then if it would be launched from earth. Also there would be possible to get some more fuel of course. Who first gets to the borders or find and colonize habitable planet - win. New clans can join at any time. And the second, clan war mode is mode where clans have it’s main bases then should be destroyed by enemy. When the game started, other clans can’t join to this server, but players can join to clans. You can’t attack base or spacecraft if your or enemy clan didn’t declare war. Also there would be possible alliances, maybe would be resources and other things to fight for, maybe would be some economic. Win the last clan with base. Maybe developers wouldn’t choose between this two ways and would just mix it.
And, finaly, private servers. It are servers then you create by yourself and can only invite players there or your friends/clanners can join there. All rules are created by yourself, maybe would be able multiplayer building.
That’s all. Thank you for reading right to the end, commenting and voting!
