Wicked Lair is just the kind of old school tower defense game that I love. I’ve always liked games I could set up and walk away from and see if my design would last without my help. Set in the old D&D style world, Wicked Lair launches heroes against your dungeon and you have to create a lair that can stand repeated attacks. It gets tougher in later levels when the combined attacks of the heroes starts to tear through your defenses. It’s free right now so you don’t have any excuse to not give it a try.
