SubSpace is a 2D space shooter online game developed by Virgin interactive Entertainment and released in 1997. SubSpace incorporates quasi-realistic zero-friction physics into a massively multiplayer online game. It is no longer operated by VIE; instead, fans and players of the game provide servers and technical updates. The action is viewed from above, which presents challenges very different from those of a three-dimensional game. The game has no built-in story or set of goals; players may enter a variety of servers, each of which have differing objectives, maps, sounds, and graphics.
In this game that requires a Windows OS, Players fly, fight, and play a variety of games with spaceships.
Gameplay
SubSpace players control one of eight ships which are equipped with weapons and a variety of special abilities. Players interact with each other in zones, which are typically split into multiple arenas.Players in each arena are then divided into teams; friendly ships appear as yellow, while enemy ships appear blue. The keyboard is used exclusively for control of the ship and use of in-game chat functions.
Although each zone can have its own unique style of gameplay, certain basic gameplay mechanics are ubiquitous throughout all zones.

Map elements
Each arena uses a 20×20 map as the field of play. Some arenas may use the entire size of the map, while others may enclose the players in a smaller space. A coordinate system (A-T horizontal, 1–20 vertical) allows players to easily identify and communicate where they are on the map.
Maps may contain obstacles such as walls or asteroids which cannot be moved or destroyed. Maps often use gates, which open and close at random or regular intervals. If a player’s ship gets caught in a gate when it closes, the ship is relocated (“warped”) to a random location on the map.
Safe zones allow a players to evade enemies or simply take a break from the game. While in a safe zone, a ship cannot take damage but also cannot fire. Most safe zones have a time limit; if a player stays in a safe zone too long, he is kicked from the game and must rejoin the zone. This prevents players from camping out in a safe zone and leaving their computer idle for an extended period of time in order to maintain their state in the game.
A flag or ball may be present as well. Their importance and role in the game depend on the zone.
The most common map elements in SubSpace are prizes, or “greens” (for their green color). Prizes allow players to upgrade their ships and gain special weapons or abilities. While prizes are generally plentifully scattered throughout the map, the upgrades or abilities they award are randomly selected by the zone.
