Syphon Filter: Dark Mirror is a string of successes all combined into one great experience. It all starts with visuals that are pushing the system about as far as any game on the PSP has managed to do so far. Characters are well-designed, though level architecture is the real star here. While you’re kept on a straight path throughout most of the game and the levels are small, there’s still a lot of variety to be found. There’s so much going on in levels (like zip-lines and areas you can climb), that you rarely feel confined to the level’s small size.
Dark Mirror contains a ton of voice work, most of which is presented through chatter during missions. You are constantly sending and receiving messages to other team members, reminding you about mission goals as well as keeping you updated on changes. Overall, the writing is good, though there are moments where the typical, cheesy “action movie” phrases pop up. Consider yourself warned.
Music sounds great and is as dynamic as the gameplay. During gunfights, it will pick up in tempo, only to subside once they’re over.
