I had a go and it's as hard as I remember!
Running south onto the soccer field I'm quickly assaulted by the game players themselves...they're easy enough to pick off but the sound of the chopper nears! It screams in throwing grenades everywhere, killing all but one of my men before scurrying away.
My lone soldier gives chase but arrives too late; it's already landed and is taking off again. My man decides this is not the place to be and heads south to the land of the megalomaniacs. These guys chuck a few spears before being dispatched by my man....but they keep streaming out of their lairs. Too bad my soldier forgot to pack his grenades! But wait! There's some handily laying nearby...he better make a run for it before the chopper gets hi....
Too late they're all dead again.
