Icarus looks like a great survival. Been playing the beta weekends and I'm not disappointed. Any chance of a server here?

Games have to hit 3 thresholds to be hosted with this provider. To be honest, most other providers have similar requirements. Just those requirements are a bit looser depending on size of developement team and hardware availability.

Does the game have a following large enough to offset the research and development costs for the panel deploymenet?
Does the game offer an official Linux deployment?
Is the game long term sustainable?

This used to not always be the case, at one point both ATLAS and PixARK were hosted here. Both deployments were eventually removed from the service, with ATLAS never making it out of beta.

As Icarus is a drop in drop out Co-OP game without a server spec sheet on their product info page, it's highly likely that any portal hosting the game is doing so similar to how Valheim servers first started. Actually, Valheim server still are largely little more than a glorified phantom console keeping the instance open.

So with that in mind, the odds of Icarus being a hosted game here are low. But, upon hitting those above thresholds it's a possibility.
