Defeating shielded Cabal
When Cabal Phalanxes raise their shield, shoot the circle emblem in the middle of the shield to take it down and inflict some damage, making it much easier to kill them.
Floor Is Lava mini-game
First, successfully complete the campaign to unlock The Tower. In the walkway of The Tower courtyard is a pile of random items. When you get close to these items, a message will appear saying "Don't Pick Me Up." Pick up an item to get a notification saying the "Floor is Lava!" The ground will now be lava. If you land on the ground, the screen will turn red and you will take damage. If you stay there too long, you will eventually die. Avoid the ground by jumping on boxes, pallets, or use the railings while making it to the nearby blue marker in The Tower. Reach the point to complete the mini-game and unlock the "Quickness" buff, which allows you to move quickly and jump higher.
The Sparrow
To unlock the Sparrow before the end of the game, you have to get it through a Bright Engram. Bright Engrams are earned by leveling up. You can also purchase them with Silver, which is bought through microtransactions using real money. Turn the Bright Engrams into Tess Everis at The Farm to decrypt. There is a small chance you will unlock a Sparrow. To buy a Sparrow after completing the game, find Amanda Holliday in The Tower - Social Sector. She sells Sparrows. The Tower becomes available after completing the main campaign and defeating the final Boss. The Sparrow is a one-person mount a guardian can summon from their inventory to get around more quickly. Weapons cannot be used on Sparrows, but boosting into opponents will inflict damage. Your Sparrow cannot be destroyed. If you leave it behind, you can simply summon another one.
