ZDR is riddled with secret passages and destructible blocks that hide upgrades and shortcuts. Always be on the lookout for suspicious-looking walls, floors, or ceilings. Use your Scan Pulse frequently to reveal hidden blocks. Different types of blocks require different weapons to destroy: standard beam, missiles, bombs, Speed Booster, or Power Bombs. If you see an area you can't reach, make a mental note and return later with new abilities. Thorough exploration is key to 100% completion.
