The 990-TAC is the secondary shotgun in RE9 — higher single-shell damage than W870 Police (500 vs 400) but smaller magazine (4 vs 5). Best for hordes and one-shot kill builds. Slug round upgrade extends effective range. Found in Chapter 7 Raccoon City.

How to unlock

Buy from Raccoon City alley shop (Chapter 7) for 10,000 currency. Higher base cost than W870 Police but stronger per-shell damage.

Upgrade order

Slug round upgrade FIRST — adds long-range capability. Then T2 magazine. Skip T3 if W870 Police is already T3.

Best charm pairings

Predator (+10% to wounded enemies) + Iron Skin + Crafter’s Touch. AR-style charms don’t apply.

vs W870 Police shotgun

990-TAC wins per-shell damage and slug round range. W870 wins magazine size and post-v1.02 spread buff. Pick 990-TAC for boss-focused builds, W870 for general use.

Best boss to use it on

Titan Spinner Phase 1 (slug rounds at range), Chunk Phase 2 (close-range burst), Plant 43 spore phase (single high-damage shot to core).

Insanity NG+ viability

990-TAC + Crafter’s Touch = sustainable per-shot damage. Smaller magazine makes Iron Skin charm mandatory for survival between reloads.
