Tower Keep: a free tower defense game online

Tower Keep is a free tower defense game that plays in your browser. Raiders walk a winding road toward your gate, and you build towers to stop them.
Every raider that reaches the gate costs you lives. A brute costs two and a warlord costs five.
Also called: tower defense game, tower defence online, castle defense game
How to play
- Press the arrows to move the build cursor around the field.
- Press A to open the build plan, which shows the tower's range. Press A again to raise it. On a tower you own, A upgrades it.
- Press B to swap between the four towers, or to sell the one under the cursor for sixty percent back.
- Bolt is the long-range sniper. Mortar is the slow splash gun that cannot see fliers. Frost halves enemy speed. Beacon has no gun but makes nearby towers hit harder.
- Press START to send the next wave early. You earn two gold for every second of prep you skip.
Keyboard: arrows, A and B. Phone: the on-screen pad.
Tips
- Put towers where the road bends so they watch more road.
- Mix tower types so you have slowing, splash and sniping covered.
- Place Beacons next to your best towers.
