In Track 9 of Hi-Fi Rush, Chai catches up with Mimosa and faces her in a boss battle on the main stage. The track is a short one, and the boss fight takes up most of the time players will spend on this level.
Still, there are a few hallways between the start of the track and the showdown with Mimosa. This is long enough for Hi-Fi Rush to insert a few collectibles, and if players aren't careful, they'll need to replay the level later if they want to grab them all.
Track 9 Collectibles in Hi-Fi Rush
The first collectible is right behind Chai at the start of the stage. Turn around and look at the wall to spot this stylish bit of Graffiti Art.
Part of the hallway leading to Mimosa's dressing room is closed off by construction. Head straight forward instead of climbing the barrier to find an Armstrong Circuit.
Now climb over the barrier and jump straight down to the hallway. The first Vlog is on an amp case just to the right.
After jumping down, turn around and head back into the construction zone. There's a Health Gauge piece waiting to be picked up. Players can see it through the mesh when getting the Armstrong circuit, so it's not that hard to locate.
The second Hi-Fi Rush collectible Vlog is in a tricky location. At the corner where the hallway turns right and leads to Mimosa's dressing room, players will see a shop. Right across from this shop is the vlog on a bench, which is concealed from view by a stack of musical cases. The only way to spot this vlog is to walk up to the shop and look around or tilt the camera straight down while approaching.
The last collectible in this track is on the far side of Mimosa's dressing room. After Chai puts on a shark costume, he goes through a 2D section where he's trying to reach the main level of the stage. Early on, there's a part where Chai jumps down and has to climb back up. Near the top of the climb is an overhang that makes it hard to jump up and to the left. However, a double jump will get around this overhang and allow Chai to reach an Armstrong Circuit.
Players can spot this circuit by jumping over the dropping spot, but jumping around the overhang is the only way to reach it. And if players got every collectible on this list, they'll have nothing else to look for during Hi-Fi Rush track replays.
Hi-Fi Rush is available now on PC and Xbox Series X/S.
