Ark: Survival Evolved- VaulTech Base- Strongest Base Design. - BOSS Approved. This video is not about the biggest base in ark, it is about a strong design that takes lots of explosives to get through. This base has been altered and improved upon since this video was made. This base was built on a 6x gather pvp server. This is my 1st real attempt at a base of this style, and I just wanted to share this design and show some other defensive measures that I commonly use in base defense in the crazy world of Ark..
