Concrete Bowling - Version 2.0 Backed by a stable physics engine, you will be able to accurately simulate advanced bowling techniques like hooking, action, entry angle adjustment and breakpoint management. Change balls weight and hook potential to handle the lane conditions. Play with CPU random settings or choose the lane oil pattern and friction. Three different throwing systems: 1) Parametric. Set direction, speed and rev rate before clicking a button to shot, like in a billiard game. 2) Mouse-based (dynamic release). Just drag the mouse over a layout of the lane to set trajectory and velocity for the ball. Then drag it again to set the rev rate. In this second phase the direction of your dragging will simultaneously define the rotations about both the Y and the Z absolute axes. The system will help you to perform a steady release. 3) Arcade. Mouse based and extremely intuitive. Everything is just play and fun. Basically an unlimited variety of throws can be simulated. Minimum system requirements are 450Mhz cpu, 64Mb ram, 8Mb 3d video card, DirectX8.1 or greater.
