Syphon Filter: Dark Mirror [PSP]

As with past entries, bonuses (typically more powerful weapons) are doled out for using weapons and stealth techniques efficiently. That the stealth component of the game is even worth working toward makes Syphon Filter stand out among PSP titles. Since Gabe's weapon set can be customized before each mission (after earning a few bonuses), the experience can change noticeably from one run through to the next. Old favorite gadgets (like the taser) also return, and Gabe's principal weapon, a rifle featuring various utility darts, adds great flexibility to each level.

Sony Bend has also outdone almost every PSP release in terms of presentation: Dark Mirror is gorgeous and nearly without hitches. The levels aren't huge, but feature a wonderful variety of locations, textures, and multi-tiered design, complete with scalable surfaces, ziplines, and dark corners for hiding.

The last Syphon release, The Omega Strain, was heavily geared towards multiplayer, and Dark Mirror is no different. Through a very elegantly designed and easy to use lobby, gamers jump into variations on deathmatch, a couple of team-based objective games, and Rogue Agent, a version of tag. What makes it work is thoroughly implemented voice communication (with a USB headset) and (in the case of Rogue Agent and the team games) a simple yet very entertaining sense of design.

That sense of design pervades Dark Mirror, making it the best shooter yet released for the PSP. Don't be put off by the learning curve, which demands a bit more effort at the front than most action titles. Once Syphon Filter's rhythms are familiar, you'll find depth and replayability in spades.
