The first Death to Spies game was challenging, Moment of Truth is a lot harder. I am still on the first level (don't laugh)
Everywhere you go you have to change into another uniform or they get grumpy at you. I managed to get into the SS building, then got the drivers uniform then the Pilot wanted his plane refuelled, spent some time trying to figure out what to do but yeah
...
So I turned my attention to Pilot #2 and managed to knock him out and hide him in a box... then the AA gun guys got upset at me
This game is hard, but extremely fun
the attention to detail of the level is great, it certainly has come alive with all the animations - I love that in a game! Those little bit of unique activities give the AI some sort of life in the game (Red Faction has really been the only other game I have seen that in, ... and maybe H&D2 to some extent).
