So much death. Humanity has suffered so much at the hands of the Covenant. The merciless aliens have slaughtered billions and left the UNSC, humanities guardian angel, in sheer and utter disarray. A single setback is all it would take to bring humanity to its knees. Is this our future? Our inevitable fate? Not if humanities greatest heroes have anything to say about it!

The Ancients and The Immortals by Metal4k reviews
A race eons older than any race known has arisen once again. Having the ability to reach across dimensions they pull great Heros from their respective realities and force them into a contest. However, as the contest unfold dark secrets are revealed, and a far more ancient, a far more evil threat is beginning to surface. Lots of action between many heros from different series.
