Forgive the awful wordplay, but Moon looks stellar. The character models are sleek, the texture work is impressive, and the environments provide subtle contrasts with each other, from the dead, desolate surface of the moon to the luminous, pulsing hallways of the alien underground. The weapons look fantastic, and they look even better when you're using them. There are some full-motion video sequences that effectively show off the game's graphical prowess, but save for the opening cinematic, these FMVs usually involve exploding bosses. Be that as it may, it's not a problem - watching a boss go down with a bang never gets old in this game. On top of all of this, Moon runs at a steady 60 frames per second.
Moon's sound design is hit-or-miss. Some will love it, others will hate it. The voice acting is very wooden and stale, but it plays such a minimal role in the overall package that it isn't that big a deal. The sound effects, however, are superb. Your weapons (75% of which are alien in origin) have distinctly unique sounds - they perfectly fit the look of the guns and the manners in which they are fired. To top that off, your footfalls are marked by loud, hollow, metallic thuds, which is appropriate, considering the main character is wearing a pressurized space suit. The soundtrack is the most interesting part of the audio design, and probably the most polarizing part, as well. If I had to describe Moon's soundtrack in one word, that word would be "experimental." The soundtrack is... noisy. Actually, it's more than noisy. Sometimes, it's outright cacophony. It is an often discordant blend of industrial noises and wild electric oscillations. It gels with the game's atmosphere nicely, but sometimes that's just not enough, and sometimes you may find yourself wondering what the hell you're listening to. However, when the soundtrack settles into a recognizable form, it borders on perfection.
