I already submitted this to the EOW Files! Not mine though, made at the official forums! I played it for myself and it does work!
Here what you get according to the maker:
"It unlocks 4 calamari cruisers and lets you build the tanks and awing and that mkii gunship thing I also changed the space map to have 3 star destroyers its still pretty easy despite my best efforts to make it impossible to win. Also the rebel base is a level 5 base now so you can load up on ships but any over 25 and you have to use reinforcments in the space level."

A MOD for the Demo already... Well some people didn't hang about huh! Also, why didn't / wasn't the e-mail in one part? You (or whoever) e-mailed it in three seperate sections! I'm in the process of uploading it to the site now, however. - I will not add it until I know you have permission to release it.
Just so you know there is a mod out that allows you to build your own ISDs, yes thats right, Imperial Star Destroyers. :D Oh and the venator model is ingame and modded in, ill make a mod for it.
 Sorry posted before I added link: http://www.lucasforums.com/showthread.php?t=158864 or the direct download http://rapidshare.de/files/11407089...UNLOCK.rar.html
It may say VSD, but teh ship is not, just look at the dang size!!!
Wait, so there are now two MOD's?
Oh there are more than 2, those are just the 2 ive posted. My No-Intro mod http://chr0n1x.no-ip.info/eawnointro.rar
The Calamari Mod works well. Clarification on what you get from it: You start your galatic battle with 4 Calamari Cruisers basicly. You're then able to produce -A-wing -Assault Mk II Cruiser -Land Speeders(sadly these do not work during the land battle so no joy =/ The Empire now have 3 SD's and the Space station. There is also a significant increase in enemy fighters due to the SD's hangar's. So those A-wings and Corvette's all seem to play a role after all ^^ You're not able to produce the Calamari cruisers yourself since they can only be built on 4 designated planets in the game, and you control none of the 4 planets in the demo ;) Anyhoot, good mini-expansion for the demo, hope we'll get some more expanding, preferable even get the ability to revert so that you could play the Empire instead of the Rebels during the 3 jump campaign, im ichy has hell to fool around with my own SD :P, but i guess ill have to wait another month. Gief ze and ze "look i r ur farthar!" already :D
Hey, about building the mon cals, I made a small mod that can do that, I can build them, ill put it up if you want.
Well now that wouldn't be fun now would it :P. Mon Calamari Cruiser cost = 4000 and -5 on the population cap. The thing thats currently bugging me is that you can't choose what ships that'll enter the battle first, and you'll often find yourself with only 2 cruisers at the start. Another thing i've noticed, those Assault Frigate MkII ships are damn near worthless!, i did alittle test where 3 Frigates engaged a SD and 1 Tie fighter squad, the Frigates got hammered with with the SD loosing 3 hardpoints and the Tie squad loosing 3 units. Also, the Shield Regeneration function that most of the Rebel ships have seem to do nothing at all. The ability states that it will increase shield regeneration for a short period of time but when i activated this on a Nebulon-B Frigate who had 50% shield, it gained nothing whatsoever Im still fooling around with the balance issue fighters are causing. I stil can't believe that SD's don't have any anti-fighter lasers and when confronted with 3 x-wing squads an SD will simply get shot up in no time really. The fighters lasers seem to drain shields a hella lot better then any capital ship. This theory was proven when i made 15 x-wing squads in the "Mon Calamari Mod" and aside from the Tie Fighters causing some minor loses, the X-wings were triumphant against 3 SD's, 1 Space Station(lvl 2 i think), and 20 squads of mixed Tie Fighter/Bomber. I sence that the huge weight put on ship combat vs diversity in this game will be a big "-" in the long run. Who the hell wants to pump out Nebulon-B frigates when you can build Mon-Calamari Cruisers?.
Yeah, of course, mon cals are powerful. Are you using Victory SDs or Imperial SDs, Imperial ones can use a Tractor Ability to slow/stop a cap ship, sitting duck! Anyway, i can also add the Death Star and Venator Ships to your starting forces, Venators cannot be built (yet) because they are intended for missions only.
 And other planets, and AI, they will build ships and spacestations above planets. :)
Am currently using ISD's. I'd love to test the stuff you can pump out :) Tho im stil not able to access the Imperial side, only through Tutorials which i'd rather not got through more then once :p Anyhoot, Ya can post it here or drop me a msg if ya want me to give ya further testing info regarding the different ships. :)
