Demo V0.3.1 is available now on Steam! I've just released the update with two new towers to help hold back the horde. There’s a Machine Gun Tower for pouring rounds into the horde, and a Slow Grenade Tower to slow the crowd down while your guns get to work. New tower power research lets you make your defenses stronger, and missions 3 and 4 now have explosive barrel stacks you can set off with a direct rocket hit. I've also made the research screen easier to read, with a pulsing border around upgrades you can afford. If you played the first build, I'd love to hear what you think of the new toys. The demo is free on Steam, so please give it a go :) https://store.steampowered.com/app/4220070/ https://www.youtube.com/watch?v=_tEHG3Ocn80
