One Turn Kill Game Complete Achievement Guide

The One Turn Kill Game Complete achievement is an unlockable milestone tied to finishing high-difficulty runs by defeating Rita and your clone at BIAS 20. Clearing this objective requires optimizing your 20-card deck to handle single-turn combat limits.

What Are the Requirements for the Game Complete Achievement?

The Game Complete achievement is a completion objective earned by defeating Rita and your clone at BIAS 20. In the Steam Community forum, players discussing how to trigger the unlock confirmed that completing standard runs or defeating the 99,999-health training dummy is insufficient on its own. Reaching the finale requires activating modifiers until total BIAS reaches 20, confronting Rita, and winning the subsequent clone battle within the game's strict single-turn parameter.

Because enemy counterattacks quickly end the run if a battle is not resolved immediately, every encounter on the BIAS 20 route demands reliable damage loops. Tracking intermediate accomplishments in your achievement guide records will indicate whether prior prerequisites, such as reaching Rita at BIAS 20, have already registered.

How Do BIAS Difficulty Milestones Lead to Game Completion?

BIAS levels are escalating difficulty modifiers that scale enemy encounters throughout the campaign. Data from the Exophase achievement list tracks 18 total achievements for the game, including several milestones tied directly to defeating specific BIAS 5 encounters before tackling higher totals.

Completing each BIAS 5 boss achievement familiarizes you with the counter play required for individual enemy archetypes. By the time you increase total BIAS to 20, minor miscalculations in card draw economy or resource cost will prevent you from clearing the board before the enemy acts.

Which Deck Strategies Clear BIAS 20 Encounters?

Deck construction in One Turn Kill is restricted to a compact list of 20 cards. On the official One Turn Kill Steam store page, developer DenDen specifies that drawing cards from the deck costs card uses, creating a system where aggressive drawing must be balanced against available actions.

Winning at BIAS 20 requires disciplined deck building focused on repeatable synergy:

1. Assemble consistent draw engines that generate more action economy than they consume.
2. Upgrade your core offensive cards at every opportunity to reduce reliance on long, fragile chains.
3. Test rotation consistency against the scarecrow to verify that your hand can reliably cross high single-turn damage thresholds without running out of cards.

Once your deck reliably defeats the final encounter sequence under maximum BIAS pressure, the Game Complete achievement unlocks upon the conclusion of the clone battle.
