Best Units to Prioritize
Building a defense that can survive the late waves comes down to smart unit choices rather than just fielding your favorite characters. The golden rule early on is to prioritize units with area-of-effect attacks, since the game loves to throw dense clusters of enemies at you that single-target units simply can't chew through fast enough. Sonic and Shadow are both excellent early-game picks thanks to their strong speed stats, which translate into higher attack frequency. Just as important — and easy for newcomers to overlook — are support units that buff the rest of your roster; a well-placed buffer can make a mediocre lineup punch well above its weight. Resist the urge to blow your premium currency early, too. Hold it for the limited-time units that appear during events, as those are often the strongest in the game. Ultimately, a balanced team pairing reliable damage dealers with solid support is what carries you through the toughest stages.
About Project Sonic TD
Project Sonic TD is a fan-made tower defense game on Roblox that turns the Sonic the Hedgehog universe into a full-featured strategy experience. The core loop will be familiar to any TD fan — you collect and upgrade units modeled on iconic characters, position them thoughtfully across maps inspired by classic Sonic zones, and dig in against waves of enemies that grow steadily more punishing. What gives it staying power beyond the nostalgia hook is active support from its creators, who roll out regular updates packed with new characters, maps, and events. That steady stream of content is a big part of why the community has stuck around, treating it less like a passing novelty and more like a game worth mastering.
