1 person hosts then invites friends from there. Set it to invite only if you don't want any randoms to join. They can also join your game when you host a game or if you're in one.
You can't simply form a party then go together in one of the versus game modes, but with time, people can switch over your team
No. There is no option to "host" a mult-player game (I am not talking about Garden Ops here which is limited in number of players and completely impractical for LAN parties). The only option I see for multiplayer is "Search" for games that already exist. This is broken and does not allow a group of 5-7 friends to play together.
Randomly searching for a game and inviting 6 friends before the slots fill up is impractical and not a solution.
This game needs a patch that at a minimum allows a player to host a multiplayer game with his friends before opening it up for others and Ideally a party system that would keep everyone together as they move from game type to game type.
Currently this game effectively has no support for playing multiplayer modes with friends.
