Instructions
Defeat all the villains and search their locations carefully. Most, but not all, of the hidden spiders will be found on walls.
Web swing to ledges, arches and out-of-the-way areas. Hidden spiders are often high up.
Look inside trains and crates.
Pay close attention to shadowy areas. Spiders are often hiding in dark areas.
Collect eight hidden spiders in each chapter except the tutorial and the final boss fight for a total of 96.
