DOS Games Discussion

I don't remember the name, but it's about world war one.
Similar to the Panzer, it's played on a hex board. The goal is to capture headquarter of the other side. There also supply depot to capture as well.
Most unit are land unit, with some maps that has water/ships, air unit are available at the later stages/maps. You only play as Allied or the Axis. And they use a passcode to unlock future stages/maps.

I only remember the picture, so if you have any screenshot or picture of the box, that will be great.

Any help will be appreciated~!

it's a turn-based game.
goes like
p1 move -> p2 move -> p1 attack -> p2 attack

It's the Great War: 1914-1918 by SSI, it uses Bluebyte's Battle Isle engine.
