How to Unlock “Will it blend?”

Steam's official wordingOfficial

Push 15 people into hacksaws in Lethal Rebound.

0.8% of players have unlocked it — very rare.

What the wording tells us

The wording gives a number and no time frame at all.

Compare it with "Full Pack", which says "a total of" — that qualifier is absent here, so neither a single-round reading nor a cumulative one can be settled from the text.

One piece of arithmetic is safe: a lobby holds at most four players, so at most three opponents exist at any moment, and fifteen pushes cannot each involve a different victim.

What players report

CommunityCommunity guides, not official material.

Both guides describe blades that bounce around the room; Deltia's Gaming adds that players can push one another.

What the official text does not say

Community accounts do not settle these — they are gaps in the official wording, and we would rather name them than fill them in.

  • The official text does not say whether the fifteen have to happen in one round.
  • The official text does not say whether the count carries across rounds.
  • The official text does not say how repeated victims are counted.

Worth knowing before you try

  • This one depends on another player being in a particular state or being the target of your action, so it cannot be set up alone.
  • Local sessions played before 2026-08-13 may not have registered this achievement — registration in Local mode was broken until v2.1.1.
  • Very rare is derived from the global unlock rate rather than from anyone's judgement of difficulty. How the tiers work →

The simulation

Push the other players into the hacksaws and stay clear of them yourself.
