A dismally watered-down, broken 'remake' of a what was a great stealth game on consoles.
Multiplayer, co-op, heat vision goggles, saving anywhere, mission loadouts have been removed. How does this game even qualify as a remake when it removes or ruins more than half of what the actual game had? The enemy AI is laughably stupid and you don't even need to bother about being stealthy - the enemies sometimes don't even notice you when you walk past. The graphics also happen to be bad and dismally dark. Even with the brightness at maximum setting, you can only see properly if you play in total darkness. And the 3D effect is , for the most part, non-existent; turning on the 3D slider to the maximum setting just might make you think that there is a slight effect in there somewhere.
At least the controls are better than Essentials. You can control the camera with the face buttons, move with the circle pad and the touch screen is also used to interact with some things. But the enemy AI is so bad, the game would have been easy even if the controls weren't good.
The only good thing about Splinter Cell 3D is that, no matter how hard the developers seem to have tried to ruin the game completely, Chaos Theory was still a great game. And thought it's a shadow of its glory on the 3DS, the story is still good and the voice acting is still great. The remixed soundtrack is somewhat welcome, even though I myself prefer the original soundtrack. Even then, Splinter Cell 3D is hard to recommend to anyone; even those who liked Chaos Theory.
