Overall the game looks good, but is lacking in major details. Granted the game isn't going to look as stellar as on the consoles, but at the same time the game world is a little too flat -- even for 2D. Levels are rather bland and can at best be described as utilitarian. Some variety can be seen as you go from zone to zone, but repetition does tend to settle in within each area. There are a few attempts to jazz up some locales, but really -- how many flags can one person have in a house? Some other elements just don't make sense, such as the big square pole sitting in the middle of a room. Character animations, especially those of Sam, are smooth and spot on. Though a lack of variety does settle in at times, the animations for some of Sam's new moves more than make up for guards who either stand, run or do some kind of 'shocked and awww hell... you're going to kill me now' stance.
Splinter Cell: Pandora Tomorrow really won't make you clamor for a headphone jack on you GBA. Background music is threadbare and what you do hear isn't great. Sound effects are limited to gunshots mostly (of course, the number of times you can use your gun in the game can be counted on one hand).
