Collect sun, plant your defenders down five lanes, and stop the advancing horde from reaching the house on the left.
Enemies push left along five horizontal lanes toward your house. Spend sun to plant defenders: producers that generate more sun, shooters that fire down their lane, and tough blockers that soak up damage. The siege fights back, a flood can drown a lane and block planting, a freeze can stop a lane firing, so react and replant. Survive to the final massive wave to win the level.
Garden Siege recreates Plants vs. Zombies, released by PopCap in 2009 and designed by George Fan, which took tower defence off a winding path and onto five straight lanes.
Everything hangs on the sun economy. Sunflowers make the currency but shoot nothing, so every early decision is a bet on how long you have before the first zombie arrives — plant defence too soon and you are poor all level, too late and you are overrun. Because lanes are independent, a single mistake is survivable but never free, and the game's difficulty is almost entirely in what you planted ninety seconds ago rather than what you are doing now.
Garden Siege is an original free browser game in the lane-defense tradition, with a resource economy and lane-disabling hazards across two difficulties. Just open and play.
