About Klaus Veen's Treason

✦ AI summary

Klaus Veen's Treason is a social deduction game where Innocents hunt for clues to expose hidden Traitors while the Traitors work to eliminate everyone before they're caught. With multiple classes offering different abilities and special roles like Detective and Doctor adding strategic depth, each round becomes a tense battle of investigation, deception, and survival.

At the start of each round, players must uncover the Don's killer by finding Clues. Delivering enough Clues to the Clue Processing Unit reveals a Traitor. Traitors conspire against the Innocents, Detective, and Doctor. Traitors win by eliminating all Innocents, while Innocents win by identifying and eliminating the Traitors.

What Steam players say

Recent verbatim reviews from Steam — separate from playze.io community reviews below.

✦ AI summary

Klaus Veen's Treason is praised by players who do play it as a fun fusion of Counter-Strike mechanics with Team Fortress 2's art style, featuring interesting additions like Zombie Traitors and a Doctor class alongside mafia-themed map design and lore. The main complaint is that the game suffers from a small player base, with many feeling it's been overlooked or forgotten despite being worth playing, though some note minor issues like the character choice between Eds feeling inconsequential and audio settings quirks.

10/10 Game. The guns feel good, it has a lot of skill expression and can get really silly at times. Basicaly TF2 if it were among us.
