BRAZILIAN DRUG DEALER BEFORE 4: DEMONS FROM THE PORTAL TO HELL I OPENED ARE STILL IN THE FAVELA AND NOW I HAVE TO SAVE MAMADAS FROM RONALDO

Brazilian Drug Dealer Before 4 is a fast-paced first-person shooter made in the style of 1990s games and built on id Tech 2, the engine used by the original Quake. It is a standalone expansion to Brazilian Drug Dealer 3 and is presented by its developer as a tribute to Brazilian mods and bootleg games of the 2000s, Brazilian music and the fictional band Mamadas. The story follows on from the previous game: after a celebration in Heaven, the band is kidnapped by a character called Ronaldo McDalest, and the player must rescue them, recover their portal-opening car and clear out the demons left over from the earlier invasion.

Movement borrows from Quake, with a dash and a double jump available to keep the player mobile against zombies, armed demons and various possessed Brazilian characters. Returning weapons include a berimbau, a payphone that fires coconuts and a gun that launches paper aeroplanes made of money, while new additions include a slingshot loaded with a bowl of feijoada and a flamethrower based on chimarrão. New enemy types include a pair of riders on a motorcycle, television mice and possessed football team mascots, alongside returning truck clowns and possessed singers. Health is restored by collecting pastel and cane broth found around the maps.

The campaign consists of 18 stages covering the state of Rio de Janeiro, parts of São Paulo, Salvador, Hell and Heaven, each with a number of secret areas, some of which can only be reached through rocket jumping or double jumping. All campaign maps support cooperative play and deathmatch through Steamworks, with friends joining by invitation and no port forwarding required. The developer states that the game will continue to receive monthly content updates, as was the case with the previous title.
