N v 2
To be an effective ninja, one must possess three things: speed, agility, and a healthy supply of liquid gold coursing through one's veins. In N v 2, you can put these skills to the test in 500 levels full of relentless enemies, deadly traps, and of course, gold. N v 2 is the follow-up to the original download version published by Metanet Software back in 2005, and plays practically identically to the original high-difficulty platformer, with the addition of a new co-op mode.
Each of the 100 "episodes" consists of five levels, all of which must be completed in 90 seconds or less. Move around with the [arrow] keys and jump with [Z] to hit the button that opens the exit, and get out of the room as quickly as you can. Each piece of gold will add two precious seconds to your life, so be sure to grab as much as you can. And as for the blue drones, weapons turrets, and red mines scattered around the room? AVOID THEM. Bumping into these will kill you instantly, and your progress in that level will be reset. You've got an unlimited number of lives, but being blown to bits when you're so close to the finish is never a fun feeling, so be careful out there.
N v 2 adds a two-player co-op mode that allows a friend to join in the fun. For this mode, player 1 uses [A] and [D] to move and [left shift] to jump, and player 2 uses [,] and [.] to move and [N] to jump. Both players' efforts are cumulative, and only one player has to reach the exit for both players to be successful. Nonetheless, the levels remain as tricky and deadly as ever, so be prepared for the long fight ahead as you progress down the path of N once more.
