The Blizzard Heavy is the biggest and most powerful rocket built by OSAS yet, it probably will be able to handle your heavy payloads, if not, well... this is not exactly the most powerful rocket in the world soooo, yeah, that's it :)

This version come with our mobile base, the Avalanche Mk-2, you can download it separately here.

And if you want you can see my video launching the Avalanche Mk2 to Cylero using the Blizzard Heavy here.
