## Description

Type 0.25*x, sin(x) or x^2/40 on the math keypad, press FIRE and watch your curve fly across the battlefield. Bend it over walls, around pillars and onto the enemy. Miss, and you see exactly where your function went, so the next shot is better.<br><br>PLAY YOUR WAY<br>• Versus the computer: four difficulty levels, from friendly to ruthless.
