Bug Bombs are unique turrets, in that they are not upgradeable and can only be used once. They cost $200. When the food stash drops below 75, the turret explodes, and deals 200 damage to all the bugs on the map. They take 15 seconds to activate.
This turret is useful for beginners, to survive onslaughts of smaller grubs.
They are difficult to use late game, as a regular turret would have to be sold to make room for it, and then the Bug Bomb still takes 15 seconds to activate.
This is relatively useless as a centipede will finish off your food in less than 15 seconds if it drops below 75.
- To activate manually, eat food until the stash drops below 75 food.
