Terrible for 1v1 vq3 / osp as once you have the rail and can camp the RA and RL, it's pretty much impossible to overcome.

I'd love to give this is a 4, because we use to play this on excessive and it was one of our favourite maps - very fast. but the design and texturing is still a bit plain as far as maps go, and the scale and item placement is questionable in standard q3, but in excessive, it rocks!
