Syphon Filter 5 is the answer to Metal Gear on the PS3

Gamer:

"Syphon Filter was one of the most popular franchises on the PSOne back in the day. It was also once considered to be a direct contender to Metal Gear Solid on the PSOne. However, after a long slumber on the PSP, the game may make a next gen comeback to give the Metal Gear franchise a run for its money.

I have fond memories of the original Syphon Filter game developed by Eidetic studios (now known as Sony Bend). You could say that the first Syphon Filter game put third person shooters on the map. Back in 1999, Syphon Filter was considered to be Metal Gear Solid's direct competitor in the stealth-action genre. Both games were released three months of each other so it was natural that the games would be scrutinized and compared."
