The Omega Strain isn't one of the PS2's crowning graphical feats. Though a few areas look nice and there are a number of nice graphical touches, the overall package isn't much to gawk over. My biggest complaint is the drab feeling the game gives off. All of the textures in the game are low res and washed out. This is complemented by a color palette that is limited to mostly dark colors. Even some of the street lamps and illuminated store front signs look dull. This isn't to say that The Omega Strain is devoid of any good, graphically. It's easy to tell that character models have received most of the attention. I'll get into this a little deeper later on, but one of the best things in The Omega Strain is the amount of character customization available. Your character starts out as a nameless, faceless... well, everything-less persona. At the start, you're limited to a select number of enhancements, but as you progress, you'll unlock new outfits, hairstyles... you name it. Another cool aspect of character models is that they show real time damage. Take a few hits, and he'll bloody up a bit. Get to within an inch of your life, and he'll hobble around in a bloody mess. And, for those keeping count, the 'diaper-walk' animations have finally been fixed.
Music isn't one of The Omega Strain's strong points. In fact, the music is so subtle and low-key at times that you won't even know it's there. Everything else sounds great -- especially the non-English speaking characters who manage to deliver an excellent performance without sounding too over the top or like a stereotype.
