Presentation is top notch. Michael Ironside returns to voice Sam, though the performance is a bit weak. He's still the same gruff-voiced character, though at times it feels like he's channeling his inner Christian Bale. Sam tends to grumble through his lines, making it hard to shake the feeling he's just going through the motions.
Conviction utilizes a "projection" system to flash objectives and goals throughout levels. The idea is to streamline gameplay as much as possible, and for the most part, it works. A few story sequences run a little too long, but the system is effective. It's an especially cool effect when used to offer glimpses of backstory or convey complex emotions without heavy-handed explanations. It's sometimes easy to miss, but sound cues will usually let you know if something important is happening.
The game also uses color to great effect. When in the shadows, colors fade out, leaving behind a washed out black and white image. Depending on how well your TV is calibrated, it is sometimes hard to see while in the shadows, though you can always adjust things for look. As with the projections, the effect works and is infinitely better than a stealth meter.
