In MAP02, we don't get to use the motorbike we saw. Instead, we get to meet the cannibal mutants. For now, these guys basically just seem like Pinky replacements with tamed Imp replacements, but in Ashes: Afterglow we'll learn that Mutants are a much bigger threat than anyone realised.
~~Timestamps For Secrets~~
†: "Secrets" that don't count towards the Secret%, but might affect the Items%.
01:56 -- Do some tricky jumping from the hotel balcony, over a broken wall. This leads to a new secret in the garage next door, with some Food in it.
NOTE: Beware the drop at 03:34 - I believe this cuts you off from the first secret if you missed it.
04:50 -- Behind the last red curtain, break the suspiciously different wall. Jump in to find Health and small Shotgun Shells.
†05:09 -- Next to the Bronze Key, go through the vent. I believe the armour fragments on top of the dumpster count towards Items%.
06:18 -- In the diner, go into the Men's room and head through the vent at the far end. Leads to armour fragments and the Jackhammer.
†06:50 -- In the diner kitchen, open the gray shutter, as it contains Food.
08:24 -- After the large battle, open the blue garage door to find an extra area. Search thoroughly for a tiny door that leads to a Collectible, worth a huge amount of Junk.
09:44 -- In the clerk's room in the gas station, look for an offset wooden wall. It contains pipebombs.
10:17 -- After blowing up the alcohol still, dive into the corner behind the fire to find a 100 Armour pickup and a stack of Food.
NOTE: In the final area, despite him being an ammo-sink this early, you will need to kill the large Cannibal for 100% Kills.
