Summary

Killing Floor has a TrueGG Rating of 94.9%: the positive share among 292 reviews written in the last 180 days by players with 20+ hours, close to Steam's overall 95.2%. Players who really play it broadly agree with the headline number (all time: 98.4%).

Reviews written under 2 hours make up 11% of the total, with 79% positive. The early hours do not split opinion much.

Negative reviews most often mention community and co-op and boredom. Positive reviews praise how fun it feels and performance.

Among Japanese-language reviews, the TrueGG Rating is 98.6%, similar to all languages.

Re-weighting reviews by trust signals (playtime, length, how the game was obtained) barely changes the rating (96.1% adjusted), so Steam's number is not noticeably distorted by key giveaways or throwaway reviews.

All figures come from Steam's public review counts, and topics are counted with our published dictionary (no AI). Data as of 2026-10-19.

Why it is rated this way

What drives the rating

Complaints center on the game's design (Boring / repetitive). These rarely change with updates, so the rating likely reflects the game itself. Judge by whether it suits you. It is also a game many people bounce off early (early reviews are much less positive than those of players who stuck with it).

Counted from 315 recent negative and 600 positive reviews in Japanese and English, using our published topic dictionary. No AI is used. Topics overlap, so shares do not add up to 100%. Sarcasm and nuance are not detected, and this does not show cause and effect.How we count
