Milk Mclane, well right now all the concepts for the Remnant are in my head.

But yeah, they're really cool.

Admiral_Kiernyc, you shouldn't wait long. A capital ship (battleship to be exact) is in da works.
Gamerking345, the mod will be released in three episodes. The first will see the Xin invade the known systems of the galaxy we worked so hard to rip to shreds so far.
The second episode will introduce the Remnant and the third will bring the Hegemony into the fray.
This is done so that players don't have to wait a year or more before they can (hopefully) have some fun.

Bss08380, the redesign continues. For an ingame version of that same model, I decided to bring some purely organic surfaces into play. I like the effect - so all surfaces where you can see windows will lose the techno look and get a pure organic flesh look. Coupled with a subtle effect where the actual windows slightly bulge out of the fleshy mass, it gives a whole new air of alien menace to the ships. Screenshots coming soon.
If it isn't obvious, I am sort of bent on details. In my opinion, too many mods settle for too many compromises to save time, and result is often sub-par to what it could have been. Little things like making your ships look the best you can make them look, not skimping on effort to make immersive special effects and so are important. They add to the overall "polished" feel and that's important for any game, be it a mod or otherwise.
General_Sherman, thanks.

Sylenall, you're not too late as Titan concept has not been finalized yet. Anyway, it is still in the works, so nothing has been decided yet. What I definitely want to do is make Titans special. Whether through research, resources requirements, level requirements or all three (or combination of either) is yet to be decided. A Titan is an extremely powerful weapon. To give them to players too early in the game is to water down the challenge. So steps must be taken to ensure that a player can get a Titan only late in the game, when they will actually need them.
As for multiplayer, since the Last Stand hopes to be a sort of "unofficial" expansion, all new races are balanced for play with the vanilla factions. So basically, you could play against others playing vanilla races with no issue, something you cannot do with, say, a Star Wars mod since their ships are so very different in terms of firepower and defense.
