Giant Killer is a free online turn-based fantasy adventure where you build and upgrade a squad of heroes to take down increasingly powerful enemies, including massive giants that will test every tactical decision you make. Combat plays out in rounds where timing your attacks, knowing when to dodge, and stacking the right defenses separates a quick death from a clean victory. Each battle rewards you with resources to strengthen your roster and push further into the game.

What keeps Giant Killer interesting is the upgrade loop. You are constantly making choices about which hero to invest in, which skills to prioritize, and how to balance offensive power against survivability. Dodge mechanics add a skill element on top of the strategy, so paying attention to enemy attack patterns actually matters. The turn-based format gives you time to think, making each mistake a learning moment rather than a frustration.

It suits players who like games similar to classic tactical RPGs but want something accessible right in the browser. Search terms like free fantasy hero upgrade game, online turn-based adventure game, and browser RPG strategy game all lead back to exactly this kind of experience.
