Attack Retrieve Capture (ARC) was a free multiplayer, 2D computer game created by John Vechey and Brian Fiete, who would go on to co-found PopCap Games, as a college project and was later published by Hoopy Entertainment in 1995.

Initially ARC was hosted on a server rented out by Hoopy at Ulink.net, an internet service provider in Sacramento, California.

Clients ran it via HFront (Hoopy Front End), a program downloaded to serve as the game to support multiplayer mode.

But by December 1999, World Opponent Network (WON) had acquired ARC and began to run another beta test.

During this time, WON attempted to make ARC a source of income, by adding advertisements into the game interface.

[3] In recent years, a devoted community has made efforts to revive the game by rebuilding its engine.

These updated versions of the original game have been released under the names "Spark" and, most recently, "Armor Critical" [4] On July 16, 2007, Sierra Entertainment posted a news release on their website[5] expressing intentions to terminate multiplayer support for several Sierra Heritage titles (including ARC) as of August 16, 2007.
