Finished the game on both Hard and Crushing difficulty today!!
On these difficulties, Nathan could take much less damage than Normal. On Hard, I estimate about 4-5 bullets meanwhile Crushing allows for only 2-3 bullets and the recovery time takes much longer. These difficulties force the player to keep moving around from cover to cover more often and take out as many enemies as fast as you can which is pretty challenging.
After finished Crushing, I replayed the game AGAIN on easy to complete the trophy collection. I was left with "200 Kills using GAU-19" and "Steel Fist Expert". The first is a feat easy to complete because you can simply purchase the GAU-19 from the "Store" under "Bonus" and fire away. But the second, I didn't know which spot is the best to do it. Thank to Trambient for his suggestion in Uncharted 2 GameSpot forum, the best place to do it is the level "Siege". To be honest, I lost count and I was sure as hell it wasn't my tenth kill using steel fist but I got it unexpectedly anyway.
My final two trophies were the multiplayer ones. I've got the game for nearly 5 days but I have never touched on the Multiplayer mode once. The first experience on the mode was just AWESOME! My first game was a TEAM DEATHMATCH and it was hectic, action-packed and thrilling. There was a lot going on there in just 8 minutes... The objectives was to complete 50 kills! My first multiplayer game wasn't so noobish as expected. Thanks to my Single Player training. (Hell, I played it 6 times). With that said, the Single Player really does prepare the players for fast multiplayer action... The Co-Op modes were really well done as well. I didn't expect it to be that good but there Naughty Dog did it... They put separate dialogs for the mode which make the usual boring straight-to-objective multiplayer modes come to life. Although the essential elements of the stages were inspired from Single Player Campaign, the developer make some changes here and there making the map more challenging.
After completing a Co-op match and a Competitive match, I've got all trophies on Uncharted 2!! Oh yeah, there is a player skin that only unlocked once you've got the Platinum Trophy and it can be used on Multiplayer Mode!!!. It's a present surprise, I couldn't have guessed it. Although, I've completed everything there is to do on Single Player Campaign but I'm sure as hell I'm not quite done with the game yet... This game just keep offering good stuffs!!
This is the type of GREAT game that worth every bucks spent I haven't seen for a long long time!
