Players are able to select a Misión which will then put them (and any others in the lobby) into the matchmaking system. Once the matchmaking system has found an appropriate session the player(s) will do one of three things: host the mission lobby, join a mission lobby or join a session in progress. If the player is put into a lobby, the mode selector will change to 'PLAY NOW' and begin to flash; this lets the player start the game. If the session is not full (i.e. does not have four players) then other players may be placed into the mission Escuadrón by matchmaking (assuming that the mission objective has not been completed). When playing a mission node for the first time, the matchmaking systems will not put the player in a session in progress. The number of Escuadrónes already in the mission is displayed next to the mission's name and is only displayed while in Public mode.
Players are able to start a mission at any time and will not be put into the matchmaking system. In this mode only the player's contacts and clan members will be able to join (either via player invite or joining the player's session).

Players are able to start the mission at any time. In this mode, no other players may join the session. If the player enters the options screen, the game will be paused, unlike the previous game modes. In earlier builds, certain enemies would not spawn at all.
Improved networking code to work around the OS delaying network port reuse; previously some users were forced to use arbitrary ports which rendered UPnP or manual port-forwards useless and prevented connections.
