A quick guide on unlocking the character Rex.

Unlocking Rex

First you will want to find and equip the Fuel Array from the rear of the escape pod.

The Fuel Array is a very dangerous piece of equipment that blows up either upon activation or when the player goes below 50% of their health bar. This detonation instantly kills the player and destroys the Fuel Array. Items like “Dio’s Best Friend” will revive you after the explosion, however the equipment will be lost. The Fuel Array can thankfully be dropped and replaced with another piece of equipment, just remember to pick it up again before teleportation.

You will need to survive and continue doing the teleportation sequences until you arrive at the “Abyssal Depths”. Towards the top of that map, there are several floating islands that can be reached via geysers. On the highest island, there is a broken robot that can be interacted with.

Once you interact with the broken robot, you will unlock Rex and receive the “Power Plant” achievement. Congrats you now have Rex unlocked, I’m so proud of you.

Useful Tips

Play on the easiest difficulty

There is no shame in playing on the easiest difficulty. You bought the game, you make your own decisions about how you play it.

The easiest difficulty raises the player’s health regeneration and lowers the amount of damage the player takes.

Play multiplayer

With multiple people on your team, they can draw enemy fire towards them and stop you from going below 50% of your health bar. Be advised, dying and respawning does not bring back the Fuel Array.

Avoid certain items in the multishop terminals

Certain items only activate or get destroyed once you reach low health. Items like the “Power Elixir” are useless considering you cannot be reaching low health.

However, items like the “Delicate Watch” are very useful since the item will only be destroyed at low health. You should also avoid grabbing items like the “Shaped Glass” because it lowers your max HP.

Find and use equipment barrels

Orange equipment barrels can be found scattered around most maps. Use these barrels to purchase a new piece of equipment. Replace the Fuel Array with your newly acquired equipment.

This will free yourself of worrying about the health restrictions. Just remember to grab the Fuel Array again before you teleport to the next stage.
