Alien breed 3d II ported to another platform

[Hammer]

Hi

I'm not a real coder but
it seems that on aminet there is the complete source code of the game Alien breed 3d2
so...my questions are:
is theoretically  possible port this wonderful game to windows or another platform using the source code on aminet?

if the answer is positive...why nobody done it yet?...it will be a difficult task?

thanks

There's Unreal Engine 3 based Alien Breed series....http://www.youtube.com/watch?v=DmJL8uztqWo
