TagPro
TagPro is a free-to-play online multiplayer capture the flag video game originally designed and programmed by Nick Riggs. The first version was released in February 2013, after Riggs began experimenting with software platform Node.js. The game is named after one of its three obtainable power-ups. It follows the basic rules of capture the flag, along with some modifications, including power-ups, spikes, and other map elements. Gameplay Players spawn on opposing sides of a map after being assigned to a team. Each team consists of up to four players, for a maximum total of eight players per game. The player controls a ball using the WASD keys or the arrow keys. Players may obtain power-ups and interact with the various game elements, using them to their team's advantage or to hinder the opposing team. In the traditional game type, players must transport the enemy's flag from the enemy's spawn area to their own spawn area, avoiding enemy players and hazards. In an alternate game type, neutral flag, there is only one flag that both teams compete over to bring to their respective-colored end zones, typically located on the opposite side of the map from the teams' respective spawn area.
