Interesting premise for a sequel, I assume we're going to see the soldiers job to the monkeys for a while before there's some kind of typical action sequel motive, like the mastermind is a friend of a child of a pharmacy survivor, but I think it will be fun.
Since he can't run, I wonder what sort of role Sacchi will play as a protagonist? He seemed like a "I'm charging head on!" sort of character in the first, and the backstory intrigue from the first has already been solved. Maybe he'll be killed off?
