Evaluation

The Hundred Line -Last Defense Academy- launched on Steam on April 24, 2025. The only DLC released alongside the game is a soundtrack and an artbook — both shipped on launch day, and neither represents story or gameplay content. No additional DLC has been announced or listed on the store. Since launch, the developer has been actively maintaining the game through a series of patches: a critical crash fix in early May 2025, a post-release quality-of-life update in late May 2025 (adding battle skip options and fixing progression bugs), and a significant feature patch in June 2025 (Patch 1.1.0, adding Chapter Select, a new battle mode, and UI improvements). Korean language support was announced in December 2025 and delivered in April 2026 via version 1.2.0, with a follow-up bug fix patch (1.2.2) in May 2026. All post-launch activity has been patches — improvements to accessibility, quality-of-life features, language support, and bug fixes — rather than new story content or expansions. The developer has made no announcements about future paid DLC, expansions, or additional gameplay content. There are no unreleased DLC entries on the store. The game appears to have launched as a complete narrative experience, with the developer supporting it post-launch through polish and accessibility updates rather than content additions.

About this game

Project Extreme x Despair is here! "Kazutaka Kodaka" and "Kotaro Uchikoshi" comes a brand-new adventure game!

Takumi Sumino is a totally average teenager living in the Tokyo Residential Complex, a place where every day is much like the last and nothing bad ever happens. All that changes when freakish monsters attack the town and start wreaking havoc. A strange creature calling himself Sirei appears and offers Takumi the power to protect those he holds dear... All he has to do is stab himself in the chest!

The next thing he knows, Takumi is in Last Defense Academy, a school in the middle of nowhere surrounded by a wall of otherworldly flames. He and 14 other students have been drafted into the Special Defense Unit, a team tasked with keeping the school safe for the next 100 days. How much are they willing to sacrifice to take back their normal lives and save the world from the grotesque school invaders?

The curtain rises on 100 days of war and despair...

Extreme Despair-Filled Endings

Takumi's choices will decide his future, but there's no telling what kind of consequences these decisions might have...

Defensive Battles

When the invaders attack, it's up to you to protect the school in SRPG battles.

Use each student's unique Specialist Skills to turn the tide of battle in your favor!

Free Time & Exploration

Spend time with your teammates to deepen your bonds, or explore the wilderness and ruins outside the school.

You can even use the items you find to craft gifts and get even closer to your allies!
