X-Morph: Defense

X-Morph: Defense lets you build walls. Not in a Minecraft sense, in the sense that you can physically reshape enemy pathing by dropping barrier segments across the map, forcing waves to take longer routes past more of your towers. That one mechanic changes how you think about tower placement entirely. You are not just asking where is the best spot for this tower, you are asking how do I want enemies to reach this tower. Add a top-down shmup combat layer where you pilot an alien ship between waves, and you have one of the more inventive hybrids in the genre. Local co-op is supported too, which my regular group appreciated when we tried it.
