3 The overall replication process should sustain itself for an indefinite amount of iterations
Indefinite can mean both not determined or infinite.
It can not make infinite of course, because at some point the Universe according to current standard model will cool out.
But apart from that no problem, as long as the physical conditions exist to support it.

IDK I think resident evil sounds like a more interesting title anyway.
Biohazard is just a generic term, and sounds pretty lame for a game title IMO.
