Very good, it's really in-depth combat and all.. Like 1st you start off with this guy in a sortof Special ops mission to scout the place then he pretends to be all cool then gets himself killed which makes a Nuculear bomb start to count down then you have like 5 minutes to defuse it and make it blow up inside the launch pad to save the world then you get caught or something and sent to prison then you escape
I'll leave the rest to you to figure out =D
