The graphics were very nice. Fallout Tactics features 3D rendering capabilities similar to that of Diablo II, with the ability to use colored lighting effects and anti-aliasing. Running the game in 1024x768 was very pleasant, and I got a great amount of field view, but setting it to 800x600 afterward didn't feel very constrictive either. Using the higher resolution didn't seem to invoke a performance hit at all on my systems, so if you have a larger monitor (17"), or you don't care about your eyes, then using the higher resolution is probably a preferred option.

Occasionally I would see instances of a body or other element on the map being improperly lit, but this didn't seem to happen too often, and it didn't really bother me. Also present was the occasional redraw bug, where a prior screen element (Like text or the mouse cursor) would not get erased after being moved. This went away easily whenever I just scrolled it off the screen, though. And while this isn't directly related to graphics, some of the death animations seem kind of silly. Granted, a shotgun could very well rip someone in half, but if they're lying on the ground when you kill them, they shouldn't leap up into the air to fall back down first!
Sound was really good, typical Fallout fare. Just like the prior two games, the audio tracks leave a haunting sense of the wasteland lingering in your mind, enhancing the game experience. The music also changes dynamically, picking up the pace if you get into a battle, for instance, and drilling into something much more empowering. Even better, the audio engine uses MP3s for background audio, so the game's soundtrack is right there on your hard drive to be listened to. As a final capstone measure, the engine allows you to put your own MP3s in a custom folder to be played during the game. This is the first time I've ever seen such a feature implemented.
The voice acting was standard-fare military forcefulness with the Brotherhood, and civilianish with the other peoples. One element I do miss from the prior fallout games was the interactive conversation, where you would sometimes be able to watch video of the listener's reaction, and communicate back and forth by selecting questions and responses. I feel it would have added extra depth to this game, and could have been used in missions where, for instance, you are sent out to pursue a certain target or locate an objective, but you don't know where it is. You would have to go to a nearby city and inquire of its whereabouts among the locals.
