If you play a hell of a lot of Halo 3 (Like the DailyJoypad staff do), then it is certainly worth investing in these maps, but if you don't, then it could be a total waste of 800 Microsoft Points. Then again, why would you even be looking into downloadable content for a game you don't play a lot? In Daily Joypad's very own humble opinion it is worth a purchase just for Orbital. And if you are into forging then Sandbox is a must-have. Assembly is kind of just tagging along for the ride, but who knows, you might like it more than this reviewer did. Overall the contents of Mythic make for yet another decent downloadable pack of tasty Halo 3 goodness.
