Does anyone know which version of Unity 3D was used for the game? The free version (originally $200), or the Pro version (currently $1500). Thanks in advance to whoever can answer this.
have dynamics shadow and normal map?! sure is pro!
Normal maps are not Pro.

I think it is free. They have high quality of textures and models and those doesn’t require the pro version.
I’d say Pro, I don’t remember seeing any Unity Watermarks on their webplayer demos.
indeed, pro 
Not to say that it couldn’t be done in Free, sure it would lose some (perhaps a lot) features, but I think you could achieve something like that.
Definitely pro - the shadows, Duke, the shadows!
Yep, shadows. Certainly pro!
Pro or even source code…
I played this and its very polished, the most polished Unity effort I’ve seen.
Shadows/effects aside I don’t see any reason why they wouldn’t be using the pro version.
They are for sure using Pro version. I am sure that their game would gather more than 100k in income which means that they need Pro licence even if they have no shadows or posteffects in game.
Thanks a lot guys, I’ve also received the same answer at the Interstellar Marines forums. It must be Pro they’re using, due to shadows I have just now seen. Guess it’s time to save up. I’m looking at creating a game based on Blackwater or a game like X3 using a mix of Blender3D and Unity3D. Thank you guys.
While I’m certain they are using Pro, I just want to point out that projected sales are irrelevant to the $100,000 turnover limit on Pro. The EULA states that “a company cannot license Unity free if they had a turnover in excess of US$100,000 in their last fiscal year”, which means if its your first year using Unity free, you can release a game and make a million dollars (good luck with that), but the following year you have to buy a Pro license if you want to continue developing with Unity.
It’s academic though, since I’m sure if you make over $100K one of the first things you buy will be Unity Pro anyway.

True, but I’m sure it will pay off more to get Unity Pro first, that way it looks its best, thus making more money.
If you develop a whole game using Unity Free, then later buy Unity Pro, do you have to re-do the whole game or just add the extras that it gives you?
Unity Free and Pro are the same exact application, the features are just disabled. So it would just be a matter of opening your project and flipping some switches to turn on shadows and postprocessing effects, etc. once you activated your Pro license.
Oh thanks for explaining that. So this means that if game is created and there is lets say 200.000$ revenue does this means that there is no need to purchase Pro at all? Putting in consideration that this is first game with totaly fresh company.
The game looks very impressive from an “indie” studio. I think they are at least a team of 10…(looking at the FAQ, they say 8 fulltime developers - I suspect they outsource some of their stuff). I would imagine they got the Pro version of Unity…
No, that means you NEED to purchase Unity Pro in order to sell it and distribute it the next Fiscal Year, if by $200.000 you mean 200-thousand. For example, you JUST put it out on market, you can make up to $99,999 within the whole fiscal year and not have to buy Unity Pro. If you make $100,000 or more after that first full fiscal year you NEED to buy Unity Pro. If you don’t purchase it after making $100,000 or more your first fiscal year, it gets taken off market and I imagine some sort of lawsuit.
