Spider-Bots send out periodic pulses on the map in Spider-Man 2 to hint their locations, making them tough to find.
Spider-Bots are more collectibles in Spider-Man 2 that you can find across New York City, especially if you are looking to achieve a 100 percent completion playthrough.
The biggest challenge you face in finding all of the Spider-Bots is that their locations are not marked on your map. If you get close to a bot though, your map marks an approximate area for you to comb.
Considering that they are small in size and easily missable, you are probably still going to find it frustrating to find all 42 Spider-Bot locations in Spider-Man 2.
Collecting all Spider-Bots will unlock The Message secret quest and award you with Funky Wireless Protocols trophy.
