Invasive Species
Steam
Invasive Species is a silly, hectic, and sometimes difficult, couch co-op tower defence game. You and your friend grow plants to defend your Grandfather's greenhouse against wave after wave of the Alien-Robot invasion.

Grow your plants in pots and put them into position on the windowsills overlooking the backyard and provide them with hand-grown ammunition. Robots will be shot on sight!

Invasive Species is a student project made by a group of 10 people over 8 weeks.
