How to grind Tower of Sisyphus
The Tower of Sisyphus is an endless mode added in the Ascension update. Floor by floor, score-attack, with an Adrenaline-amplified scoring system. Three trophies tied to it.
How to access
- Same portal as Ascension co-op (Helios crash). Choose Tower of Sisyphus instead.
- Solo or 2-player co-op.
Scoring basics
- Adrenaline level multiplies your score. Hits taken reset Adrenaline = score reset.
- Pickups during Score Streak give multipliers. A 30-second streak with no hits = 5x multiplier.
- Floor clears also multiply.
Trophy targets
- The Wages of Death — Reach floor 7 (the Phrike-tier boss). Manageable in 1-2 hours.
- Eternal Vigilance — Reach floor 14. Needs solid play.
- The Climb to the Top — Reach floor 20. Hard. ~3-5 hours of grinding.
Best loadout
- Hollowseeker with Portal Beam as primary.
- Pyroshell Caster as backup (huge boss DPS).
- Astronaut Figurine every time you can afford it.
If stuck: Tower phantoms are the boss enemies on floor 7 and 14. They're identical to campaign Phrike and Hyperion respectively. Practice on those bosses first.
