The H.I.V.E. Moon Base is also playable as a Tier 2 Hard Mode Alert, accessible from level 30 with a combat rating of 43 or higher (no loot is provided above combat rating 64). The Alert is substantively the same as in Normal Mode, with a couple changes, including:
- Enemy strength is appropriate to combat rating 43-64.
- Loot drops are appropriate to combat rating 43-64.
