Same, great gameplay of the Splinter Cell series
-Gameplay If you have ever played a SplinterCell game, you should know exactly what your getting into. Double Agent is very similer to ChaosTheory, so if you liked that game, you'll love this. This game isnt exactly the same, as you'll have the double agent part included. As a splintercell fan since the first game, I can tell you that this is easily becoming my favorite in the series.
-Graphics Unfortunatly, it seems that somehow the graphics in Double Agent are worse than the graphics in ChaosTheory. The graphics are still very great for an xbox game, but considering ChaosTheory, I think that ubisoft could have done a better job. Also, the night vision is very ugly for some reason.
-Sound The sound in Double Agent is very great as well. Theres more great dialog from Ironside and the music is much improved and much for cinematic than from the past games in the series. However, I did come across some problems with the dialog, as in some parts of the game, fishers voice seemed to be off when interegating the enemy. It just seemed to be a bit high rather than the usual low voice of Ironside. .
-Value Double Agent for the Xbox has A LOT of value. The single player campaign will take most players about 10-15 hours to finish. Then theres the co-op mode, which is now a lot more (4 times more) than that of ChaosTheory. Then theres multiplayer, which will keep you comein back for more.
Overall, theres less polish in this version of the game than before, but its not so bad that it makes the game not enjoyable. So if you love splintercell, you should get DoubleAgent since it offers more in single-player, co-op, and a different yet still great online versus.
