As an interesting aside, many of the characters are voice acted by Ion Storm Dallas personnel including Tom Hall, Jake Hughes, Lee Perry et al from the Anachronox team. On a related note, the music and sound effects are both well done. The music does get repetitive at times, but that's true of most games. When you compare the length of the game to the amount of music, repetition is inevitable. Combat can very often be avoided in the game, but it's unlikely that you will stay away from it altogether.
Fighting does involve a couple of very interesting elements.
One is the aiming system that steadies your aim and thus improves your accuracy as you take more time. Would-be snipers will very quickly learn that a successful head shot is fatal. The control interface for Deus Ex involves both the mouse and keyboard. If the default key selection doesn't suit your preference, re-configuration can be done quickly and easily either before you begin or during play. As a relatively complex game, Deus Ex contains quite a number of screens and interfaces for things like inventory, augmentations, ammunition selection, the auto-journal et al.
