Secret weapons

Three weapons come from outside the quest list:

  • Splitter Gun, a permanent unlock.
  • Shrinkifier 5k and Blade Gun, one-run rewards in single-player Survival. You keep them until you pick up another weapon or the run ends.

What each one does is on the weapons page.

Splitter Gun

Shots split into two fragments on every hit (details).

Unlocks once you beat quest 4.10 The End of All on hardcore. From then on it drops like any other unlocked weapon.

Shrinkifier 5k

Shrinks whatever it hits; anything below size 16 dies (details).

In single-player Survival, stay alive for 64 seconds without firing and without getting hit. You can't kill anything without firing, so you'll still be on the Pistol, and the game swaps it for the Shrinkifier.

Blade Gun

A piercing blade with an 11x last hit (details).

In single-player Survival, your first three kills of the run mark a triangle. After the third kill:

  • don't fire;
  • don't kill anything else;
  • get your health below 15 (out of 100);
  • stand within 16 px of the triangle's centre.

Firing before the third kill is fine; only firing after it counts. A fourth kill, by anything, closes the path for the run. The third kill also cancels the Shrinkifier. You don't need to be on the Pistol.

You can get both in one run: take the Shrinkifier with fewer than three kills, shoot with it until your third kill, then follow the steps above.

Everything else

Nothing unlocks HR Flamer, Spider Plasma, Evil Scythe, Flameburst or RayGun, so they never drop. See unobtainable weapons.
