Alpha Hunters is one of the modes in Crucible.
Description[]
Fight with an ally to be the last team standing! In this game mode there is no respawning - once you’re defeated, you're out. If your ally is defeated in the match you will have the option to temporarily ally with another solo player in the match by sending them a dynamic alliance request. Throughout the match the containment barrier collapses to a small centralized battlefield (the collapse point in each match is different). At the end of the match, an essence condenser will spawn in the exact center of the safe zone. This objective creates a large (4000 XP) essence plume. Once the essence has been collected, it takes 30 seconds to reset and respawn another plume. When only three hunters remain, all temporary alliances are broken and cannot be remade. Eventually two must fall and one is left standing. But don't celebrate/weep too long: it's time to re-queue and do it all over again.
