Dreadnought, the long-coming free-to-play multiplayer spaceship battling game from developer Yager and publisher Grey Box—which is currently in beta on both the PS4 and PC—is bringing a new mode to that beta for fans to try out.

Havoc mode is Dreadnought‘s take on Horde mode, where up to three players can work cooperatively against wave after wave of computer-controlled space fleets intent on taking you down and conquering your little corner of the cosmos. The twist here, though, is that you don’t know what ships you’ll have at your disposal to do just that.

When the mode starts you and your friends will be given a small assortment of ships to choose from, and usually have enough choices to have a solidly put together team of damage dealers and healers. But there’s no telling that the ships offered to you will be something you might be familiar with, or even particularly inclined to using. And every three waves, you’ll have to spin the wheel all over again and choose new ships. It adds a degree of randomness that is worthy of the name “Havoc”.

I had a chance to try out the mode, and admit to only making it to wave five with some random allies (video below), but continue to be impressed by the variety of ships Dreadnought offers. And I admit I fell victim to my own hubris, which ended up costing my team before we could take on the boss ship in wave seven. I enjoyed the fact that to combat some of the randomness, and the ever-increasing difficulty of your enemies, you could purchase boosts with points earned in battle that stack as the mode continues on. Obviously, it wasn’t enough for us to overcome the enemy AI in the mode, but as you gain more experience with the game, it serves as a critical feature that could turn the tide of a potential battle. And I, for one, can’t wait to see what combinations of ships and buffs we’ll be tasked with utilizing in this new mode.

Dreadnought will leave beta and be fully available on both PC and PS4 sometime later in 2017.
