Shell Rush

Archgun charge-rate mod

Released Oct 30, 2015

Shell Rush increases charge rate on compatible Archguns by up to 50%. Consider it for a charge-based Archgun when reducing charge time matters; it does not provide the listed fire-rate bonus for ordinary automatic firing.

Shell Rush GUIDE

Understand Shell Rush

Useful when…

  • Improve charge rate on an Archgun whose attack uses charging.

Effect and compatibility

Shell Rush provides +12.5% charge rate at rank 0, +37.5% at rank 2, and +50% at rank 3. It is a standard-slot Archgun mod with Vazarin polarity and base drain 4.

Rank investment

The mod has three ranks. The listed rank-up examples cost 20 Endo and 966 Credits for rank 0 to 1, 40 Endo and 1,932 Credits for rank 1 to 2, and 80 Endo and 3,864 Credits for rank 2 to 3. Prioritize the final ranks when charge rate is important to the weapon’s use; otherwise, a lower rank preserves resources and capacity.

How it differs from fire-rate mods

Shell Rush is specifically described as charge rate. Automatic Trigger instead lists +60% fire rate, while Magnetized Cycle lists +30% fire rate alongside +60% Magnetic. Those are different listed effects, so consider them according to the Archgun’s firing behavior and the stats you want.

Limitations and tradeoffs

  • Uses a standard Archgun mod slot.
  • Its charge-rate bonus is not listed as a general fire-rate increase.

Common mistakes to avoid

  • Assuming charge rate and fire rate are interchangeable.
  • Spending for maximum rank when the equipped Archgun does not make useful use of charge rate.
