The Psycho Gundam from the upcoming Dynasty Warriors: Gundam 2 might look intimidating, but as long as you aim for the glowing purple parts you'll be okay.
The Psycho Gundam is certainly larger than anything I recall fighting in the original Dynast Warriors: Gundam, but this clip takes a whole lot of the intimidation factor out of what might have been a tense initial encounter in the sequel, due out on the 21st of this month for the PlayStation 3, PS2, and Xbox 360. Hopefully there will be tougher versions of the Psycho in the game that do more than simply fall down and let you hit them in their private purple places until they die.
