Legend of Grimrock 2 on its way? No, it's available right now, which is even better! Though you don't have to grab it straight away. Actually, it might be wise to run the provide compatibility test and read up on what the game has to offer first.
Leading up to the release, developer Almost Human published a "Compatibility Test" -- essentially a cut down version of the game featuring the engine and a single scene, so players can make sure their system is capable of running Grimrock 2... and at an acceptable frame rate.
It's only 50MB and worth grabbing if you're unsure if your rig is up to the task.
Secondly, to prepare players for the game itself, there's a class and race overview, which looks at additions like insectoids, ratlings, alchemists and knights in more detail. It also talks about the improved class flexibility, where being a fighter doesn't pigeon-hole a character into an existence bereft of magic.
