Well we have hit a small hiccup with the launch on Early Access :)
As you may notice there isn't a Play / Install button on the page. We have notified Valve and are now waiting on a fix for it.
There is a work around for the problem, but we are hoping it will be fixed very soon. Then everyone can play Gunscape with no issues!
Stay tuned for a proper launch announcement once the kinks are ironed out.
Cheers,
Blowfish Studios.
