Castlewatch

forget the graphics, this is old school tower defense at its finest. less than the price of a coffee and hours of fun. no ads, no microtransactions, just pure strategy. it's like a love letter to warcraft 3 fans. get it, you won't regret it!!

Good cheap Tower Defense that will give you plenty to think about. Starts off fairly simple , but later mazing options have to be negotiated. Upgrades are interesting and most of the bells and whistles seem to be there. Graphics are basic, but they don't get in the way of the gameplay.

If your looking for this kinda tower defence, this is a nice one.

Seems like a fun game, with a lot going on. There are five basic types of towers, and one additional that doesn't shoot but can block the path, and eventually has a buff for near-by towers I think. The five basic types of towers have (I think) six possible upgrades, but each tower has three special types that can split off into as well, so a lot of decisions to be made. These are strategic upgrades, where you buy access to these later upgrades. The towers also allow for prioritizing targeting, a nice option. These is some variety to the foes, fliers, walkers, swimmers, which is fun, plus some seem to have special powers. I saw a walking death that seemed to summon critters as he went along. The graphics are primitive, but serviceable, and the music simple but not annoying. All in all a well thought out and fun Tower Defense game, two thumbs up. ADDENDUM: 25 hours in, and still enjoying it. A wide variety of styles and types of towers, maps and foes, as well as a deep and interest...

One of my favorite tower defense games. I love Castlewatch because of it's simplicity. I wish there were an easy mode though to really utilize a lot of your fully upgraded towers. Easy pickup, and a lot more maps than the demo. Highly recommend.

Exactly the kind of old school style tower defense I was looking for! A lot of fun.
