Will Fraxis break my knees for this?

[EternalSpark]

I'm a mapper for the Half Life Modification Alien Invasion, and since I'm an avid AC fan I decided to have a Former in an area, so that the Aliens and Military guys have something to crouch behind.

My quesiton is... is this legal?

That sounds awesome, I love both games, I dont think Firaxis will care too much...
BTW I've always wondered if Firaxis and Valve got together and made a game, what it would be like.

I don't think Firaxis will care either, the graphics mod for the new units in CTP contained exact copies of animation from Age of Empires. Microsoft doesn't seem to care about that, they have better things to do than go around policing mod packs.

Technically, it is not legal. However, if you give credit in your read.me file, you should be fine.
