Two turrets. One hole in the ground. Survive the horde together.
W / S — aim up / down

Space — fire
Q — Lava Drop
↑ / ↓ — aim up / down
← / → — power shorter / further
Enter — fire
= — Lava Drop
Zombies and demons climb out of a hole in the ground and head for your turrets. Shoot the floating gems to upgrade your cannon — homing seeker missiles unlock deep into the tree — but every upgrade tears open another hole somewhere on the map. Each of you also has a Lava Drop (Q / =) — a powerful strike down your own slope, once every 5 waves. Press B for a shared Carpet Bomb across the middle of the map, once every 2 minutes. Don't let anything reach either turret.
