Before you go berserk over the fact that I have the portal gun mod, please note that it only mentions that it is not allowed in modpacks from 1.8 upwards, where this is a 1.7.10 pack, as mentioned further up. But seeing as this is part of the permissions, here is a link to his blog to find more of his fantastic mods! http://ichun.me/
Install Dimensions Combined
Step 1
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.
Step 2
Type in the modpack name (Dimensions Combined) or paste the following url into the search box.
Step 3
Finally, click Install at the bottom right of the launcher after you select Dimensions Combined from the list on the left. The launcher will handle everything else!
