C&C3 Tacitus Revolution
The unofficial second expansion pack to Command & Conquer 3: Tiberium Wars is currently underway as the story is still a work in progress (a sectional part of this mod is finished). So far I have done 125 pages on a manual planout to do this big project; but, however, the chances of doing the development is slim if I will be able to go for it since this mod project is just too big and expensive for a RTS. Better yet, there will be at least 100 missions for the expansion mod with an epic 40 GDI mission campaign. Although the end begins in C&C4 Tiberian Twilight, the end ends there in C&C3 Tacitus Revolution.
RA3: The Final Frontier
The unofficial second expansion pack to C&C Red Alert 3, the game where it lefts off with the Empire of the Rising Sun still holding on to their destiny. With Yuriko Omega made her uprising, the Soviets are on the run and FutureTech busted, the Allies are still reeling to know what is going on with those two factions and why the time machine was destroyed by the Empire. Chances of making this is slim since the RA3 Mod SDK does not have enough resources to do this and some of the content in RA3 cannot be modified. Planout is now complete without the rest of the story including scripting and map layouts. Although proposed, there's a slim chance this will happen.
Portal Reloaded is a proposed mod for Portal 2 and the unofficial expansion pack to Portal 2. This is where Chell left off outside and just as she thought she made her freedom, she found herself in another testing lab. Although the project could be as big as the Tacitus Prophecy, the ideas of mapping and modding Portal 2 is far better and greater than any Half-Life 2 or HL2 related game. The planout is completed, but decided not to release any details. Although proposed, there's a slim chance this will happen.
Half-Life 2 Reloaded
HL2 Reloaded, aka the unofficial HL2 Episode Three, is a proposed mod for HL2 EP2 and it continues the story where it left off between the events of HL2 EP2 and a possible HL3. Although this mod may not happen anytime soon, the suggestions and ideas on what I mention in the planout are imaginatively made up. The planout is completed without an enhanced story, scripting and map layouts. Although proposed, there's a slim chance this might happen.
Dune IV Reloaded
The sequel to Dune III (known as Emperor: Battle for Dune) will bring a 40 mission campaign and gameplay will be used under C&C3 specs. So far the planout for the factions is done but the rest of them were undecided to be made up.
