You know the bit before a big battle in Total War? Where you prep for the fight by repositioning your units, choosing your formations, and making everything nice and organized. The Great War: Western Front has this too. Only, the pre-battle phase represents a month leading up to the battle. And it’s not neat, but rather the brutal reflection of ongoing conflict.
You’re not just shifting units around. You’re preparing the battlefield for the conflict ahead. You’ll dig out trenches and protect them with barbed wire. You’ll fill those trenches with infantry, and further protect your territory with machine gun nests. You’re changing the landscape for years to come, in pursuit of a marginal victory that could slowly push the war in your favor.
This is a World War I RTS, which means victory won’t be quick and easy. The mantra for is that this will be a ‘battle of inches’—marginal gains that slowly tip the war your way. Whether you choose to play as the Allies or the Central Powers, you’ll win by grinding down your opponent—taking actions that will deplete their ‘National Will’. This is the main resource of the campaign, and if either side lets it drop to zero, they lose the war.
