Start Defending in 17.waves TD
17.waves TD, a fast-paced online co-op tower defense game, is now available for a public playtest on Steam. Developed with inspiration from the strategic depth of PixelJunk Monsters and the chaotic teamwork of Overcooked, the game invites up to four players to join forces against relentless alien invasions.
The public playtest, which runs until September 22, offers access to the full game with full online multiplayer support. Players interested in participating only need to visit the game’s Steam store page and click the green “Join The Playtest” button to begin defending their base.

In 17.waves TD, survival hinges on teamwork and strategy. Each level challenges players to endure 17 waves of alien attackers. Success depends on building and upgrading towers, stepping inside them to overclock their performance, and manually collecting dropped gold during the heat of battle. Extracting resources to enhance towers and stockpile ammo adds another layer of tactical decision-making. Players can also purchase upgrades to boost their abilities and provide vital buffs to the team.
This is not an early alpha or a limited preview. The developers emphasize that 17.waves TD is a fully finished, tested, and balanced experience. By offering the entire game for free during the playtest period, the team hopes to gather valuable player feedback and make final refinements before its official release.
For fans of cooperative gameplay and tower defense strategy, this public playtest is a rare opportunity to experience a complete game ahead of launch, while helping shape its final polish. 17.waves TD promises thrilling action and teamwork-driven challenges for those ready to defend humanity’s last stand.
