Crossposted to AO3.

Halo Reach AU/Dead Space crossover. The mission to destroy the Super Carrier succeeded, without Six or Jorge dying; the marines stayed behind with the bomb. In the aftermath, all of Noble Team survived Reach, and the war. A few weeks after the victory over the Flood and the Prophet of Truth, Noble Team is redeployed to investigate an ONI monitoring station that recently went silent

The Flood and the Necromorph pathogen meet… in the body of one tired Issac Clarke floating about in the abyss of space. They would have to learn to share, or die trying. (Future Alien lemons, perhaps?)

My first cross over story, please be gentle on it thanks. Chief finds the Ishimura

Welcome to planet Rapture. Untouched by the Covenant, and Isolated from all other human life. The people who live there live life as normal. That is, until the U.S.G Titan crashes on Rapture. Then horrors and death like Rapture has never seen before begins. Who will survive and who will die? It is up to Kelly, Jake, and Sarah to decide this. The Rapture has now begun.

Carter wakes in a room to find he is in a straight jacket and has no recollection of how he got there. An introduction to some of the baisic characters that will reoccur throughout the story and more to come soon.

Alice Meets Necro. Necro Meets Alice, someone gets hurt.

Spartan A-259 Carter, wakes up in a hospital ship to face a new threat against the UNSC. Along with fellow survivor Issac Clarke, will they escape the oncoming Necromorph assault?

The Red Marker has fallen into Flood hands and Isaac now works directly with the UNSC, alongside Master Chief. Rated M for horror and language.

Its been 3 days since contact with the U.S.G. Higurashi was lost, no one knows what happened. An elite squad of ODSTs has been sent to find out what happened, but nothing could prepare them for what they would encounter aboard this ghost ship. input plz
