5. Insect Swarm – BioShock (2007)
The BioShock “Insect Swarm” defense had various results depending on which game you were playing. In the OG title, the Insect Swarm could attack enemies anywhere from 20 to 30 seconds, and even helped unveil targets pretending to be dead. BioShock 2 stepped it up a little, throwing in a feature that allowed a defeated enemy to be wrapped in an “insect bomb” trap that could actually clone itself. It proved to be very effective when you had a sea of enemies coming at you.
