The Predator's Genome. I – Legend

I – Legend! That’s what my comrades call me. Or rather, used to call me. I was truly a legendary sniper until I went blind. Medicine in our world proved powerless.

But a secret organization that opened a portal to another world offered a deal: they would restore my sight – transplant the eyes of a rare monster – in exchange for completing a contract for them. 

I will eliminate the leader of a radical sect that is gaining power in that world. It sounds simple, but it turned out that to complete the treatment, a second dose of the monster's genome is needed. 

And, it seems, the sect members are already aware of who is coming for them… But those are just details, as my sight has returned, which means… The Legend has returned too!
