While we wait for the future of patches to come to this game we also at some point will be introduced to factions.
It is unsure how many factions will be added to the game or what is in the game now will be what is allowed to choose from.
Note you can only be in one warparty per game on the website. This is for choosing a faction your heavily wanting to play more then others.
When come time to make warparties for this game depending on the active members of this game we can talk more between selves and see if we like to play in a PvP type mode.
They haven't added much yet as atom points earn for fighting others besides some "wanted" but hope they would when faction play is added to the game.
