| Depends on what you want, Splinter Cell 3 has co-op and internet multiplayer (Spy vs Mercenary) to keep the fun going, the interactiveness is pretty decent too you obtain some cool high-tech weapons and have great action moves (Eg, hang off a pipe and break their neck, jump out the water and drown them) its alot better than games 1 & 2
the cool thing is the coop actions like tomonage, one guy grabs the other and throws him across the room (to knock out a gaurd or over lasers) the coop games require great teamwork
Hitman I dont know much about, lots of diffrent-styled stealth, and prolly a good story line and guns, good interactivity but no coop to play with your friends
I'd personally get Splinter Cell
EDIT: oops voted for hitman by accident |
