In Extreme Paintbrawl, there are three game modes available to the player: Season Mode, Single Game, and Practice. Season Mode allows one to manage a team of 8 recruits through an entire season. The player is able to hire and fire recruits, buy markers, and compete against other teams for the championship in compliance with a fixed schedule. There were several flaws in this mode such as the inability to swap markers between recruits. Single Game allows the player to play a single paintball match. The objective is to score by either capturing your opponent's flag or marking an opponent. Practice mode leaves the player all alone on the field of his/her choice with no specific targets to shoot.
Extreme Paintbrawl received extremely negative reviews and is widely considered one of the worst video games ever made. In addition to its outdated Build engine graphics, it shipped with abysmal AI which often performed bizarre behaviors, such as running towards the nearest wall and appearing to do the moonwalk. Enemies also have seemingly perfect aim, because nearly every shot fired in the player's direction scores a hit. Also, although the game only installs and launches under Windows 95 and higher, the actual game is a DOS program. This often caused compatibility problems, especially with newer computers.
