Microdrones[1] are enemies in A Crack in Time. They are small Nefarious Troopers that use bolts of electricity to attack. At times, three of them will also merge, forming either a Splitterbot or a Protoguard. Ratchet and Clank fought them in various missions across the Breegus System.
Microdrones attack only in very short range and can be defeated in one hit. Early on, the OmniWrench and Constructo Pistol are sufficient against small groups. Area-of-effect weapons such as the Sonic Eruptor or Constructo Shotgun are more useful against swarms. Automatic support weapons such as Mr. Zurkon or Tesla Spikes are effective as well.
