Fight off ragdoll-zombies in increasingly difficult levels with your arsenal of unique arrows.
At the start of each level you have an opportunity to build a base with supplies specific to that level. From then on out you just need to survive until the time is up... easier said than done!
-Build forts using metal, wood, spikes, and explosives
-Fight a variety of enemies from armored zombies to web-spinning, acid-spitting spiders to skeletons carrying lit bombs
-Purchase and upgrade various arrows with diverse features. Some will chain your enemies together, others pierce through, and another type explodes on contact (theres more than those three).
