The new and updated QUAGMIRE (using OGRE Rules, no Stacking and Beaches with Swamp) and QUAGMIRE! (using GEV Rules with Stacking and Beaches with Swamp) have been republished over in the WorkShop on STEAM.

Both Scenarios still retain the "bug" that allows GEVs to use Beach hexsides and not have to stop before entering Swamp. So, if you want to see how "Marsh" works in these Scenarios, head over and give them a playthrough. If you do, please report back here and let us know what you think.
