"Steam Next Fest" is happening now and I want to let you know about some unreleased games which have demos up for the next few weeks.
1. "868-BACK" by Michael Brough

This is the sequel to 868-HACK (the Best, most satisfyingly fast roguelike). The sequel will include a "campaign" mode, which this demo omits, so this demo is basically a free, more refined version of 868-HACK.
2. "Titanium Court"

I literally do not know what this is.

868-BACK on Steam
868-BACK is a computer-hacking strategy roguelike game where your mission is to dismantle capitalism one server at a time! Use hacking powers to fight enemies, steal the servers' data, and face increasingly nasty situations before being disconnected (again!) by the richest corporations on earth.
