Conquer or Save…England!

Oct 9, 2025

What if… Germany had invaded England during WW2? This hypothesis has been studied multiple times and been ported to wargames of different sizes and scopes for years.

Now, it’s time for you to discover it with the latest SGS title, Sealion (from the German code name of the operation).

In this turn-based grand strategic simulation, you play the German High Command attempting to cross the channel, land and conquer southern England to end WW2 in victory… or you play the embattled British forces, defeated in the Battle of Britain but not yet broken and ready to put a last stand for survival… in which direction will fate move? This is now yours to discover.

Fight the a-Historical full campaign, or the two smaller scenarios covering key moments of the operation.

The game is a new grand production of the team that brought you all those strategic and operational simulations of so many conflicts. Try and enjoy a unique WW2 simulation, in the spirit of SGS Operation Downfall and other hypothetical but plausible campaigns

What is Turn 0 for besides strategy picks?

I understand that each side can pick its strategy on turn zero. But there are also air phases. Should I not do those? For example, the Germans, if they want, can launch air strikes on the invasion beaches on turn 0. They can also deploy their defensive air cover. During the British turn, they can also launch airstrikes and do defensive air cover. Is this as intended? Or are both sides to avoid doing anything but picking their strategy and then hitting end turn? Advise....

BUG: Submarines entering a port hex in France are stuck in there

I can't move them into the Channel. It says that only air units can take that path. Please check out this screenshot: https://i.imgur.com/COgWyr3.png

Option to lock cards for AI play in PBEM?

After seeing my AI defending itself from a couple-rounds light air raid by playing an "Armor Support" card which needlessly increased my stack combat capabilities (a card I was keeping in case of a difficult armoured attack) I'm thinking whether would it be possible to have a little toggle where we can "lock" cards from the AI defensive phase. Essentially something which tells the AI: "Okay, I don't want you to use this card for defence". This of course applies to all SGS games....
