Fortoresse is a multiplayer war browser game in 2D. Two teams fight in a war zone made of pixels. One has to protect the flag and the other one has to take it in a 2 minutes time limit. Each player can destroy the world or build a fortress made of pixels to protect himself and his teammates by pressing the space bar.


Jean-Baptiste Le Marchand created Fortoresse in 2008 on his free time along with two other little multiplayer games reunited on the website Extinction.fr . The website acquired its own community of fans who still play after 6 years. Sadly, as there were less and less players, the games were slowly dying out. Jean-Baptiste Le Marchand being really fond of those games, he didn’t want to let them die completly. Therefore after Atelier 801 was founded, Melanie Christin and Jean-Baptiste Le Marchand decided to breathe a new life into those games. The brand-new Fortoresse was launched in March 2014. The game was originally named "Forteresse". But with fans being used to call it with the nickname "Forto", they renamed it "Fortoresse".
