How to play campaign online in Star Wars Battlefront 2 for PC [Tutorial]

This is the explanation for how I did my campaign online let's play for this game. This is not possible on ps2 or xbox as far as I know.

Admin Commands:
/admin /addmap geo1c_c (this is used for adding maps, substitute geonosis with any id from the list below).

/admin /swap 1 (this is for swapping players to a different team, substitute 1 for the player number you wish to swap).

/admin /maps (displays all maps in the order they will be played).

/admin /players (lists the players in the game along with what number they are).

/admin /endgame (ends the game and moves on to the next map in the list).

/admin /restart (restarts the current map).

/admin /say blabla (makes admin say stuff, substitute blabla with whatever you want to say).

/admin /boot 1 (kicks the player from the lobby, substitute 1 with the number of the player you want to kick).

Map list with ids in the order they are played in the story:
Geonosis - geo1c_c (works fine but other players on republic cannot change classes).
Mygeeto - myg1c_c (all players except the host will be kicked upon starting).
Space Coruscant - spa2c_c
Felucia - fel1c_c
Space Kashyyyk - spa3c_c
Kashyyyk - kas2c_c
Utupau - uta1c_c
Coruscant - cor1c_c
Naboo - nab2g_c (players on the naboo gaurd side will sometimes have spawn issues, also enemy units may show up as allies to players that are not host but are still killable for negative points).
Space Mustafar - spa4g_c
Mustafar - mus1c_c (at the final objective (kill gizor delso) all players except the host will be disconnected).
Kamino - kam1c_c (extremely buggy, can crash, freeze, black screen, disconnect, or wipe the map of all units at any time).
Death Star - dea1g_c (all players will be disconnected upon completing the 3rd objective (capture the hallway command post) but everyone will be able to join back after the host completes the next objective (capture the plans from the rebel)).

Tantive IV - tan1g_c
Space Yavin - spa1g_c
