I actually had a few ideas already for updates and DLC:

For updates I think a lot more weapons and armor should be added especially since this game is kind of based on the world restarting. For one I would actually like to run around with like a long sword or short sword and so on I mean the world restarted basically where are the swords and maces and the other older style weapons back from the castle age I would like to see some of those. I am also a bit surprised how little guns we have, where are the LMG's, the classic looking revolvers, and so on I know we can design so many weapons now but some of the base guns are missing that could be in the game. The same goes for classic knight armor especially like black knight armor. What about possibly being able to dual wield I mean 2 swords at once would be cool or even 2 pistols if you have the strength for it. For more on armor what about being more robotic, I mean this is the future and nuclear radiation has covered the land what about having a suit that looks closer to Iron Mans, or Ultrons. What about even becoming a robot like Ultron or a synth anything is possible now.

For DLC what about making one that ties in with the new armor and weapons I listed ? Why not have a new place to explore that some of the old bones of dinosaurs got radiated and came back to life on a island away from the main land ? Maybe someone was experimenting on lizards and created real dragons, or caused there DNA to revert back to the time of the Dinosaurs ? I would like to see something like that.
