Description:

Up to 6 players, built for 2 against 4. Spawns 1-2 share the central island, around a volcano; spawns 3-6 each have a corner island. No ground route joins the two sides: armies cross by landing craft or by air. Teams and spawns are free in the lobby, and the scripts follow whoever starts where.

Mirror-symmetric both ways: the two central bases are alike, and so are the four islands.

Timed events:
- Straits: ice seals both lagoons, where the two-player side's harbours are, until the north strait thaws at 5:00 and the south one at 8:00.
- Islet silos: a missile silo on each of the two gem islets, owned by no one and guarded by two turrets, a pillbox, a SAM site and infantry. From 8:00 an engineer can capture one; its countdown is 8 minutes. A destroyed one is rebuilt, unguarded, 3 minutes later.
- Armadas (lobby: off, normal or brutal): five times, from 10:00 and every 7 minutes, landing craft and warships from the four-player side land at a beach of the central island, with a beacon and about 90 seconds' warning.
- Doomsday at 25:00, with 2 minutes' warning: every silo's countdown restarts at half its length, and the whole map is revealed.
The volcano erupts at each event (it does no damage). A line at the top of the screen counts down to each event and shows each enemy player's next launch.

Missile silos: by default up to 4 per player on the two-player side and 2 on the four-player side, each with a 10-minute countdown. Lobby options set each side's limit (none to 6), each side's countdown (5 to 30 minutes) and when silos can first be built.

The two-player side's refineries pay 50% more per load by default (lobby: none, +25%, +50%, +75% or +100%).

AI: pick Sea and Air AI, Sea and Air AI (hard, +10% ore income) or Sea and Air AI (brutal, +25%). It runs its own navy and air force, takes islet silos, builds and fires its own silos, posts three rocket soldiers by each of them and builds anti-aircraft fast after an air strike. Rush, Normal and Turtle build navies too, and the naval commander runs their warships, landings and silos. Two lobby options, both on by default. With Ally AI assist, AI players on a human's team help defend that player's base and join their attacks. With AI team coordination, AI players on an all-AI team do the same for each other.
