- 1996 - The beginnings of the clan (Pirates) -
It all began in mid-1996 with our founder, Paulo Figueiredo (ShadowBeast), and two friends, Mário Carmona (Carmona) and Alexandre (Alex). At the time, 28 and 33 kbps modems were cutting-edge internet technology, and together they formed the Pirates team to play Quake.
Three years later, in 1999, Paulo moved on from Quake and, together with a co-worker, João (Jony), decided to ‘embrace’ a new game and project: Unreal Tournament, a competitive online multiplayer game.

- 2001 - The era of Unreal Tournament with LG (Limpeza Geral) -
In March 2001, João left the clan, and Paulo invited another co-worker, Rui Tavira (Intruderman), to join his Unreal Tournament TDM team. Together, they decided to rename the Pirates to LG (General Cleaning). Just a week later, two more members—AcidFire and Waveboard—joined the team.

- 2001 - The definitive Clan name MB (Murderer Beasts) -
On June 2, 2001, Shadow decided to change the clan’s name from General Cleaning to something that reflected his nickname, ShadowBeast. With the help of Intruderman, the clan’s final name was born: MB (Murderer Beasts).

- 2005 - Multigaming - MB Gaming -
IIn 2005, Murderer Beasts expanded to include several game teams—such as Counter-Strike 1.6, Counter-Strike: Source, Medal of Honor: Allied Assault, and others—officially becoming a multigaming clan.

- Today -
The Murderer Beasts are currently inactive.
