Jerusalem's a hell of a looker for a 2004 level. And great ambience. Fisher sneaks past houses and can hear people praying, chatting, dogs barking, babies crying. Ubisoft Milan nailed every last facet of this level's atmosphere and crafted a pretty great environment for Sam to run around in. Gameplay wise, it's not as memorable. A majority of the sneaking you do is great, but you spend a majority tailing someone you end up doming before dropping into an underground lab where things go slightly downhill. Mission-wise, the train level prior is probably the peak. A relatively straightforward, short level, but it's got an exciting concept and executes the idea of sneaking around a train, going in and outside of it amazingly.
Pandora Tomorrow has been far more spy action-y than its predecessor, and I've so far been seeing it in the same lens as Bioshock 2: Good QoL improvements, weaker story. 4 more missions to go, halfway there!
