Guide to Code Vein's Ruined City Underground (Act 1, Chapter 1), including Oliver Collins boss fight strategy and item locations.
Walkthrough
- 1Advance forward from the first mistle (a point where you can save, level up, store items, or teleport).
- 2Pick up the Loss shard near a Lost body.
- 3Follow the path, fighting enemies and collecting items until you reach a split.
- 4Take the north path to a dead end, destroying boxes to find items.
- 5Return to the split and take the west path, defeating enemies until you reach a door.
- 6Be wary of an ambush near the door with 3 Lost; prioritize killing the Lost with a Bayonet first.
- 7Open the 2 chests down this path.
- 8Continue down the path, defeating enemies and collecting items, including slime-like enemies that fall from the ceiling. Use long-range gifts or a bayonet's strong attack to deal with them.
- 9Go up the ladder at the end of the path, collecting any items.
- 10After going up the ladder, purify the mistle to map the area. A path to your left leads back to the start, with a chest behind the stairs.
- 11Follow the path to the right of the purified mistle into a cavern-like area. Look for a place to drop down to find a chest.
- 12Drop down again and advance to a fork. One path leads back to the ledge you jumped from, the other to an open area.
- 13After a cutscene (scene), proceed on your own. Consider returning to the first mistle to level up.
- 14Follow the path, which splits. One path has normal-sized enemies, the other a slightly bigger enemy. Both paths lead to the same place.
- 15After the paths meet, you will find an unactivated mistle. Activating it will respawn (be brought back to life at a checkpoint after death) all killed enemies.
- 16Prepare for a large sub-boss enemy with long-range and close-range attacks. Use a long-range weapon like a bayonet's strong attack to chip away at its health from a distance, or lure it off the ledge.
- 17After defeating the large enemy, the area will be mapped. Advance north.
- 18You will encounter another Revenant who can join you as an ally. Keep pushing north.
- 19At a split path (one up, one down), take the lower paths first to defeat a slightly big enemy.
- 20Return to the upward path to ambush bayonet-wielding enemies.
- 21Face another large enemy similar to the previous one. Coordinate with your ally to take down the Bayonet wielders while your ally distracts them.
- 22Follow the path to a small room and watch a cutscene.
- 23Continue advancing, encountering slightly big enemies and slimes.
- 24Reach and purify another mistle to fully map the area.
- 25Head upwards towards the surface for the first boss battle against Oliver Collins.
Tips
- Items often appear as shiny objects dropped by enemies or found on the ground.
- The area has ledges you can fall from, which is a common way to die.
- If you die and revive at a mistle, enemies will respawn, and you will need to fight your way back. Collect any Haze (experience points) you dropped.
- The map is not fully detailed until you purify a mistle.
- For the large sub-boss enemies, using a bayonet's strong attack from a distance is effective, but be wary of their long reach and stomping attacks. Letting them fall off the ledge is also an option.
- Against Oliver Collins, plan your attacks carefully as he is slow but has strong swings. Use your ally as a distraction.
- When Oliver Collins reaches 50% HP, he becomes larger with increased attack damage. Avoid his swings and attack from a range or from his back while your ally draws his attention.
