Dopefish Forever is a fan-game created by Chris Geroux (also known as Scumsoft) with Klik & Play. It is an updated version of Dopefish Lives!, with four new multiplayer modes added. While the gameplay is rather basic, it is one of the more popular fan-games due to its humor and unique concept. It is also notable for being featured in The Official Dopefish Home Page.
In the single-player mode, the player controls a green Dopefish, who must eat all of the Schoolfish to proceed to the next level, while avoiding the Underwater Mines. This mode spans five level, the fifth featuring a Sprite that constantly fires at the Dopefish. In the fourth level, after all but one Schoolfish are eaten, Keen appears, who grants an extra hit point if eaten.
The multiplayer modes are divided into Fishfest and Dopematch, each with two-player and four-player variants. In Fishfest, the Dopefish race to be the first to eat 20 Schoolfish. Dopematch is an elimination mode, where the Dopefish eat the Schoolfish to then spit them out as projectiles against their opponents. If a fired Schoolfish hits an opponent, the Dopefish who fired it gains half a hit point.
There is a well-hidden easter egg in the game, which can be found by double right-clicking on the little circle by the T in "SCUMSOFT" at the title screen. This leads to a two-player mode featuring Roger Wilco from Space Quest, where the two Dopefish race to eat him 10 times.
