We're used to seeing ninjas portrayed as shadowy figures, most often found skulking around bamboo forests and running silently over rooftops.
Gameloft's latest arcade iOS game Ninja Up throws stealth and subterfuge out of the window, focusing instead on catapulting a ninja warrior up the side of an office block in broad daylight.
Rather than controlling the ninja directly, you must draw small elastic ropes onto the screen. These act as trampolines which propel your vertically ascending hero higher and higher.
There are girders to avoid, and weird helicopter dudes who threaten to chop you into little ninja pieces.
You can download Ninja Up for free on iPhone and iPad right now. To see what it looks like in action, check out the hands-on video below.
