This is the much-awaited sequel to AH's Colossal Arena. Originally, this game was Knizia's Grand National Derby, but two successive re-creations have added much chrome to Reiner's design. The basic idea remains intact: there are eight alien races, and at the end the only three will remain; bet on the aliens you think will make it to the end. Numbered cards, ships in this case, are played underneath the alien world cards. As soon as each alien has a power card and there's a definitive loser, said loser alien race is removed and a new round starts. This version of the game changes the abilities attached to each alien world (arena entrants in T:tA) and allows players to use power cards (or ship cards) to attack other ships or even other player's bases, which are the bet chips themselves.
