RetroTD v2 is a strategic offline tower defense game where every placement matters. Build powerful defenses, upgrade your towers, unlock permanent Research, and survive increasingly dangerous enemy waves. Choose between Desktop TD-style Open Maps, where you shape the enemy route yourself, and handcrafted Classic Maps with fixed paths. Easy to learn. Difficult to master. DESKTOP TD-STYLE OPEN MAPS Open Maps bring classic Desktop TD-style path building to RetroTD. Enemies always calculate the shortest available path from spawn to base. Place turrets directly on the battlefield to create walls, shape the route, and force enemies onto longer, more dangerous paths—but you can never block the base completely. Master three different battlefield sizes: • Open Eyes! • Open Minded! • Open World! Open Maps remove the total turret limit, while special tower limits keep every battle strategic. Gold Mines always operate at 100% efficiency. MASTER CLASSIC MAPS Prefer traditional tower defense? Classic Maps feature carefully designed fixed routes. Study each battlefield, find the strongest build locations, and create the perfect combination of damage, range, speed, crowd control, and economy. BUILD YOUR DEFENSE Build and upgrade: • Gun Towers • Rocket Towers • Freeze Towers • Splash Towers • Gold Mines • Dynamites • Claymores Every tower and support weapon has a unique role. Combine direct damage, explosive attacks, slowing effects, tactical weapons, and income generation to survive longer. OUTSMART UNIQUE ENEMIES No two enemy types require the same strategy. Face standard enemies, bosses, runners, giants, flyers, and more. Study their strengths and weaknesses with the in-game Enemy Intel system, then adapt your defense before the next wave arrives. PERMANENT RESEARCH Every run helps you become stronger. Earn Diamonds and unlock permanent upgrades for your towers, weapons, economy, critical hits, targeting, game speed, and more. Build your long-term strategy through: • Permanent Research upgrades • Military ranks • Daily Challenges • Research progression • Rank-based rewards • Monthly Diamond rewards Your Research decisions shape every future run. COMPETE ON EVERY MAP Every map has its own leaderboard. Improve your personal best, challenge players from around the world, climb through the military ranks, and compete for monthly Diamond rewards. Can you become the Legend? SURVIVE ENDLESS MODE Test your strongest strategy against an endless assault. Build, upgrade, and adapt as the waves continue to grow more dangerous. How long can you survive? PLAY OFFLINE RetroTD is designed to be played offline. Play anywhere—even without an internet connection. Your progress is stored locally and can synchronize when you reconnect. No energy system. No forced waiting. Just strategic tower defense gameplay. FOR FANS OF • Tower Defense Games • Strategy Games • Offline Games • Base Defense Games • Wave Survival Games • Upgrade Games • Retro Games • Desktop TD-style Games Build smarter.

Fun to play but definitely gets harder the longer you play. **Developer response:** Thank you very much for your review, very much appreciated. If you have any suggestions, please dont hesitate to reach out :) ### 5/5 — Awesome TD *2026-06-02* This is a great free game that doesn’t make you watch ads to play. I don’t think I’ve watched a single ad actually. This doesn’t have tons of towers or enemy types. It’s simple, but fun and easy to play. **Developer response:** Thank you very much for your review, very much appreciated :) ### 5/5 — Cool! *2026-06-01* Great updates thanks **Developer response:** You are very welcome :) ### 5/5 — Classic TD *2026-05-14* This is a fun time waster. Give it a try if you like TD games. **Developer response:** Thank you very much for your review Very much appreciated ### 5/5 — Awesome TD *2026-04-25* This is a great free game that doesn’t make you watch ads to play. I don’t think I’ve watched a single ad actually. This doesn’t have tons of towers or enemy types. It’s simple, but fun and easy to play. **Developer response:** Thank you very much for your review, very much appreciated :) ### 5/5 — Good just a little buggy *2026-03-15* I really like the game style and the simple ui. However there seems to be few bugs that while not awful are annoying. For example, I watched a few ads to be able to afford some permanent upgrades but then the upgrades didn’t work. **Developer response:** Thank you for the review and for reporting the bug. In the meantime I have located the cause of the issue and solved it right away. The upgrade was done, but when starting a new round, the game didn't reload the fresh upgrade (Only increase start coins was affected). Next release with the fix is planned to be released this Friday. Again, thank you very much. Tim ### 5/5 — A great retro game *2026-03-02* Reminds me of games I played many years ago. I’m much prefer this style to the overly busy, crazy graphics tower defense games. **Developer response:** Thank you very much, I have the same preference :) ### 5/5 — RetroTD *2026-02-15* Let me not start this with the gameplay. Tim, the owner and developer, listens to feedback and connects with his community. This game is simple and the classic tower defense. This game is worth a download if you enjoy the classic tower defense feel without the complexity of new tower defense games. **Developer response:** Thank you very much! Very much appreciated. Stay tuned for many more (simple) features that will enhance gameplay and if you have any requests, let me know ## Frequently asked questions about RetroTD ### What is RetroTD?
