Forum:Plagiarism or similarity? Honesly...

Well, I'm planning to write a sci-fi novel, and it's story would be based on an extinction cycle. The antagonists are going to be a race evil cyborgs who are all linked to a netwotk where they can share any information. this network is maintained by the Embodiment, a super computer. This computer was hacked by the aliens of the last cycle, and when the cyborgs entered to sleep after the harvest, the virus activated, causing glitches, so only a few could wake up, etc etc. My question is: With the extinction cycles and other stuff, does it look like it's just a Plagiarism of the Mass Effect base idea? I have more details but I don't dare to plan anything solid until this question is in the air...
