The last version of Outerra adds a mini-game intended to test LUA scripting in the engine. You can access it anytime with Alt+F2.
You have a bow, arrow can be shot using RMB, and targets spawns around you. Hitting the targets will give you a +10 to +50 score depending of your precision (closer to the center). Missing a target, hitting the target too close to the ground or hitting a target twice will result in a negative score.
I'd say, why not doing a little contest to see who can came up with the best score for a 5min run?
(Proof in video, 'cause it's too easy to edit the config file and change the score values).
