Operation Chaperone

Operation Chaperone is a quest Dillon take does in Rio Grande, requested by Colonel Buster. In this quest, you can't let Gun Tower 4 get destroyed.

Note: This is one of those quests that have to be taken before starting the day. If you don't take the quest, it will not be available to you. This doesn't count as a penalty.

Strategies

 * Upgrading the tower to Iron or Steel is always a good option. Use the Gatling Gun Lv.2 are a safe option, but its costs is expensive.
 * Through testing it has been found that the Megagrocks in Rio Grande will always target Gun Tower 4 first, meaning they must be eliminated quickly to preserve the tower.
