I know I have said this before but just when I thought I had seen big, here comes another one. The author states that it is for 3 an optimized for 5?? Well, with three it is going to be slow, if you use to a high kpm. You will find the weapons on the outside rings and the ammo in the inside. There is a inner ring that is enclosed around the inside, with some great sniper bunkers. The marine in the bunker is able to open and close viewports and one of these bunkers has a elevator to another area and shield recharge. Some neat visual tricks and for a big group it should handle at least 4 modes of play. The authors have a web page with a open doc readme with pics.
