Im sorry stalker zero but you are wrong. Just because its free doesn't still give you the right to do what you like with someone elses intellectual property. Try searching for mods with an aliens theme and you will find nothing and thats because fox are extremely strict on their lisence. Just because its free doesnt mean it cant be damaging to the franchise. The original mod creators can be taken to court over it. GW are also rather strict with their lisence as well however mods seem to be ok but the following game which is given out for free isnt?? TEARDOWN
