ProtocolTD

A randomized maze tower defense for 1-8 players. Every run generates a brand new maze, so there are no memorized builds and no solved metas. Shape the enemy path with blockers, build your defense, and survive all 50 waves, including a boss assault every 10 waves.

Play single player or with others in CO-OP or Competitive multiplayer through Steam lobbies, no port forwarding required. 

(LAN and direct IP hosting is also supported on TCP/7777.)

CO-OP

Up to 8 players build one defense together. Plan tower placements, funnel enemies into kill zones with blockers, and donate gold to whoever needs it most. 

Enemies scale with your player count, so communication and planning is key!

Competitive

Everyone fights their own copy of the same randomly generated maze. When the first player clears a wave, the next wave spawns for everyone, so a fast defense puts constant pressure on the slow ones. But eliminations decide the match: the last player standing wins. Sometimes stalling is the smartest play.

Your Arsenal

• Gatling Gun - cheap, rapid-fire machine gun
• Slow Trap - cuts enemy speed in half
• Laser Turret - continuous beam dealing more damage over time
• Blocker - reroute enemies the path through the maze
• Rocket Turret - explosive area damage
• Railgun - pierces everything in its lane, fires across the entire map

Every turret can be upgraded three times for more damage, faster fire, and longer range. Click a turret to buy upgrades.
