FTB Launcher

Feed The beast launcher 1.2.4

The Feed The Beast (FTB) Launcher was developed by the people who brought you the Feed The Beast challenge map. The launcher is built in Eclipse, a program for Java coding. Unv_Annihilator did a lot of streaming when he and the developer team designed and wrote the launcher.

All of the mods in the pack have been approved by the modders to be included. The FTB Launcher was first released on Saturday, Nov. 10, 2012, with a live-stream broadcast on the Feed The Beast website. The live-stream was lead by Slowpoke101, Direwolf20 and Jadedcat on on Slowpoke's Twitch channel. The stream had about 5000-7000 people watching.
