Its about a male soldier, I think its set in the future where normal soldiers get replaced by advanced soldier. And he (the main character) gets dumped into another world and he finds other people living in it.
At the end the advanced soldiers come to destroy that place but the main charcter kills them all.
P.s. He also falls in love and I remember a part where there comes a sand storm or something and he saved an old man (or someone).
Thank you
