I'm not sure from where I drew inspiration for this game, probably from the popular 'statue' game we used to play back in the school days, or maybe even the Indian festival 'Holi'.
The computer version of the game, is basically a single / two player game.
The setup:
You and your opponent are in an enclosed room. You have a 'splatter gun', which basically shoots a big drop of colored liquid (you get to choose your color). Mind you, the speed of the splat is not as fast as a bullet, it will actually be possible for your opponent to dodge the 'splats'. The gun doesn't have a long range either. Which means, you have to get close enough to the opponent to be able to shoot. And also that the gun takes time to reload. You can't just 'keep shooting'!
Apart from being able to move/run about in a 3D enclosure, you can jump off walls and land behind your chasing opponent. Because, in order to shoot, you have to be facing your opponent.
As a player, your only objective is to 'splat' color on your opponent.
The winner:
the player with the maximum number of splats at the end of a time period.
Hmm...now when I think about it, it sounds exactly like any other Unreal type frag match. But, I guess the key element here is the ability to dodge oncoming 'splats' and jump/spring off walls.
