The Apocalypse mod adds over 180 new units, structures and super weapons to the original RA2YR and will give you a completely new RA2YR experience while keeping the classic feeling alive. The mod does not require other resources to run except the original RA2YR game v1.001. This is what the mod adds in general: 64 new structures, 40 new infantry units, 17 new naval units, 20 new air units, 41 new vehicles.
Ships available to the Allied Navy.
I see the Allies brought back their Gunboats and Cruisers, and have subs of their own now.
But what's that big ship between the Aircraft Carriers?
The biggest ship is the heavy aircraft carrier, a better carrier with heavy fighters. The 4 in the corners are prism destroyers and the 2 carrier-like sized are classic battlecruisers.
Awesome! I love seeing legacy units like the battlecruisers! [Though in RA1 they were called, "Cruisers"]
