The host
Chooses “Over local network”, then Host a game. The game announces itself on the network and waits for an opponent. He can also Host a saved game to resume an interrupted network game.
In every case, the game starts from the HQ's operations table: New game → Against an opponent, then the question “Who commands the opposing side?”. The radio set's settings (map, regiments, season, time…) apply just as against the computer.
Both sides are played on the same keyboard, mouse or gamepad, each in turn: the good old hot seat.
The first player commands his units as usual, then ends the turn (Tab).
The “Next player's turn” screen hides the whole map: the fog stays honest. The second player sits down and clicks Play to reveal his own view.
Two computers on the same network (same router, same Wi-Fi): no account, no server, no address to type.
Chooses “Over local network”, then Host a game. The game announces itself on the network and waits for an opponent. He can also Host a saved game to resume an interrupted network game.
Chooses “Over local network”: announced games show up by themselves under “Local network games”. He picks one with Join, or Resume a game to pick up a shared save.
To play with someone who is not on your network. The game goes through a matchmaking server: it introduces the players to each other, then keeps their game until it ends without being able to read it, since it is encrypted with a key only the two players know.
Choose “Online”: the game asks which name to play under (pre-filled next time).
Players waiting lists the ten players closest to you (same country, then nearest time zone). Type a name to look for someone in particular, then pick your opponent. Or host a game and wait for someone to find you.
One of you chooses Private game and gets a twelve-character code (such as ABCD-EFGH-JKMN). He gives it to his friend, who types it in Join with a code. The game appears in no list.
Each player plays their turn whenever they like, whether the other is connected or not: if they are there, they watch the turn live, otherwise they see it replayed when they come back. Resume a game lists your games in progress, those where it is your turn first, and the home screen points out the ones waiting for you.
Both players must have the same version of the game. Otherwise: “Different game version”. Update the game on both sides.
On a network, the host's settings prevail, “Unlimited supplies” and “Side” included: the guest plays the other side.
Online, each player has 48 hours to finish their turn. After that, they lose the game, even if they are not connected. The time left is shown during their turn.
A player has at most 5 online games in progress, waiting for an opponent included; a new player has only one on the first day. A finished game frees its place.
On a local network, a game is saved by mutual agreement: one proposes, the other accepts or refuses. To resume it, the host hosts the save and the guest chooses “Resume a game”. Online, the game stays on the server by itself.
On a local network, if the link drops, the opponent has two minutes to come back. After that, they lose the game. Online, a drop costs nothing: the game picks up where it left off.
On a local network, leaving a game means giving it up: the game asks for confirmation. Online, “Leave, the game goes on” keeps it in progress, with the turn deadline still running; “Give up” loses it.
At the end of each turn, the two computers compare their game. On a local network, a difference is corrected from the host's game, an impossible order makes whoever gave it lose, and repeated differences stop the game without a winner. Online, a difference or an impossible order stops the game, without a winner if the other disputes it.
While the opponent plays their turn, a little game against the computer helps pass the time: tic-tac-toe, sea battle or four in a row, your choice.
