FireLine: Merge Defense

FireLine: Merge Defense brings together two satisfying mechanics — tower merging and wave defense — into a single, surprisingly tense experience. Towers don't just sit there; combining identical units creates something stronger, forcing constant decisions about when to upgrade versus when to hold the line.

Enemy waves push harder with each round, and the grid space for placing units is always tighter than you'd like. Positioning matters enormously. A poorly placed merge can leave a crucial lane unprotected right when it hurts most.

The strategic depth sneaks up on you. What starts as a fairly relaxed puzzle gradually becomes a scramble to optimize limited space, balance firepower across multiple fronts, and anticipate threats before they overwhelm your defenses. There's real satisfaction in watching a perfectly arranged formation dismantle a heavy assault.
