When you start your journey into the first Leviathan raid lair in Destiny 2 Curse of Osiris, you find yourself going down. Down, down, down you’ll go, farther than you thought possible into the belly of the great Eater of Worlds. After the descent and after the waterfall, you’ll find yourself face-to-face with the first task of this raid lair: traversing the Reactor.
The Reactor is a multi-phase encounter that mostly centers around jumping on platforms. Out of the purple, stinking goop in front of your fireteam, platforms will rise. Only one player can stand on these at a time or the platform will sink into the ooze, killing everyone on board. To make more platforms rise, you must have players on the previous platform.
Getting through this encounter is simple if you know where to go. Think of it like the way ducks cross a road together: a single file line with one duck leading the rest. Your first player is your momma duck, and the rest of you are their ducklings. There are technically enemies shooting you during this section, but they won’t really bother you much.
The first section of the Reactor is the simplest to venture across. Create an order for your fireteam.
- Have Player 1 jump on the first reactor platform.
- Wait for a moment for the second platform to rise and then jump onto platform two.
- Player 2 should immediately jump onto platform one.
- Continue this process with Player 3 following 2 and Player 4 following Player 3 and so on.
The path here is very straightforward. Just make sure Player 1 is always looking for a new spot to jump onto.
Once Player 1 reaches the end of the platforms, the notification “Reactor temperature rises” will be displayed. At this point, all of the platforms will turn red and begin to sink. Your fireteam must now run and jump onto the platform ahead. As long as you reach the final platform and the notification is displayed, the old platforms will come back for any players who died.
This is where things get a little more complex, but not much more. The first platform for part two will spawn on the right side of the safety zone.
- Have Player 1 jump on it.
- Platform two will spawn to the left side of the safety zone.
- Player 2 should then jump on it.
- Player 1’s next platform should spawn.
- Player 1 will move forward and Player 3 will replace Player 1.
Essentially, you are splitting up into evens and odds.
This will continue like this, each side alternating until one spawns in the middle. Have the odd side team jump on it, which will cause the final platform to spawn. Have Player 2 jump over to it and then run like hell to the safety platform.
Reactor 3 is where things start to get tricky.
- Have Player 1 start like usual.
- Follow the path until all six players are on a platform.
- At this point, a new platform will spawn by Player 6.
- You’ll need to reverse the order for the rest of Reactor 3. However, Players 1-3 will not be able to take a simple route forward. They will need to cut corners by jumping across other red platforms and the purple goop. Otherwise, they will sink and die.
The key here is moving and reacting fast. As soon as there are open platforms across the way, the first three players need to book it. Try and stand on the most recent red platform whenever possible, as they are all timing based. Once you have all moved farther in, the notification will pop, and you will be free to move forward.
This section really requires trial, error, memorization and communication. The platforms will rise like normal, prompting your team to jump on them. However, after only a few jumps, the pattern will get more erratic, making it very difficult for Player 1 to always take the lead. This is where communication comes into play. Players must call out when they are jumping and where they are going.
- Players 1, 2 and 3 will usually be taking the newest platforms.
- Players 4, 5 and 6 will be following behind.
- This section of the raid requires constant communication, so make sure to call out who is going where.
- Once a platform turns red, you’ll need to start prioritizing your movement, lest you sink. Tell your team you need to move and figure out who is standing on the oldest red.
After a bit of chaos, the platforms will come back together into a single file line. Follow this path until the notification pops. After all that, you’ll find yourself at the end of the Reactor.
Now it’s time to fight.
Defeating the Loyalists
Now the you’ve reached the end, the Cabal will fight you for real. Thankfully, there is no real mechanic here. All you need to do is fight progressively harder waves of Cabal. The new Osiris exotics, Prometheus Lens and The Colony, do considerable work here. Rockets and submachine guns are also great.
The key to winning this section is not being conservative. Use that Super, shoot that rocket. There are lots of Cabal to kill, and they drop plenty of ammo, so you’ll always be able to replenish quickly. That includes power ammo. After you’ve defeated the final enemies (several Colossuses? Colossi?), Calus will interrupt and grant you a small chest for your trouble.
Time to head deeper into the Leviathan.
