Carriers function as support and supply vessels and can also serve as mobile outposts with repair and recharge capabilities.
What's that? You say you want to pilot one of these shiny new vessels? Well, this is Bigpoint, so you'll need to enter a lottery via the community forum for your chance to jump in the cockpit of BSGO's latest and greatest. If you're not up for that, the ships will be available to all players on all servers after the completion of the trial period at the end of this month. You'll need to be level 40 (and in possession of nearly 500,000 in-game cubits) to get one for yourself.
