Viva la Vita: "Koei Tecmo, and Team Ninja have released a new trailer for their PSVita port of Ninja Gaiden Sigma 2. This new version adds the bloog back to the game from Ninja Gaiden 2, an easier difficulty setting in Hero Mode, new costumes, and tag missions. The game will launch later this week worldwide. Early word from is that the game is subnative resolution, without anti-aliasing. The game supposedly runs at a seemingly locked 30fps though."
