Super Coliseum P.R.O

Super Coliseum P.R.O (スーパーコロシアムP R O) is a 2006 crossover fighting game for the Arcades, GameCube, Xbox, and PlayStation 2. The "P.R.O." in the game's title is derived from Petropolis, Robot Summoner Kite, and O.K. Buster Frenzy, the three gaming series published by Namco upon which the game is based.

Gameplay
Super Coliseum P.R.O plays like any fighting game (although more like Tecmo's Dead or Alive series), but with a few twists. Attacking opponents will knock glowing orbs out of them for players to collect, with a bar at the bottom of the character's health indicating what percentage of the orbs in play each character possesses; the size and value of these orbs vary depending on the strength of the attack used. Players who collect a majority of the orbs will enter "fury mode", dramatically increasing their speed and attack power. Characters have access to a host of special moves and abilities, with certain characters being able to use temporary transformations to increase their strength.

The single player mode has the player fight through 8 rounds, 3 of which have missions with randomly selected goals; the higher the difficulty chosen by the player, the more missions are given out. Fulfilling these missions' goals rewards the player with coins that can be used in the slot machine upon defeating the boss character, allowing players to potentially unlock characters, stages, and other bonuses.

Playable Characters
The game features a total of 24 playable characters, 12 of which are available from the start. Those marked with "^" are unlockable.
