This pack was made for Tachyon a good friend of mine. It will be updated when bug fixes are needed and when the pack simply needs to be updated.
Installing a modpack using the Technic Launcher is easy. If you don't already have the launcher downloaded, visit our download page to get the latest version.
Type in the modpack name (Tachyon Pack) or paste the following url into the search box.
Finally, click Install at the bottom right of the launcher after you select Tachyon Pack from the list on the left. The launcher will handle everything else!
