Pro: many new nuances (only the occasional, meaningless eagle attacks nerve), usual, long game, villain Pagan
Con: German Syncro somewhat flat, still going (to) a lot of time for it's traveling, repetitive dialogues with random events & Radio but some Buggs acts, sometimes a bit "knitted with the hot needle".
What I'm missing: I've never understood why you need annoying mountains, where around it crashes forever awkward needs or to death (after all, there's the gyrocopter and NEN piton). Scenic also little difference to part. 3
Overall, however, solid and captivating continuation of the series, but without real highlight. Parts 2 & 3 of the story definitely better. Therefore, "only" 4 *.
