We were playing a co-op crafting/survival game that had the weapon fusing mechanic from Tears of the Kingdom. However we quickly found out that most bosses were trivialized by shooting arrows fused with random materials. After defeating the latest boss, the rewards for doing so spawned in our hideout. Aside from some random junk, there were also new attachments to play with. The dark blue flame had a lock-on mechanic while the red one was your standard explosive attachment.
