This modification, released in 2004 for PC (Microsoft Windows), is a single-level shooter experience built upon the foundation of Doom II: Hell on Earth. As a mod, it represents community-driven content that expands upon existing game frameworks, offering unique gameplay scenarios.

Mod Type and Core Experience

I.C.T.O.A.N. is classified as a "Mod," meaning it is user-created content that alters or adds to an existing game. This particular mod leverages the engine and mechanics of its parent game to deliver a distinct, self-contained challenge. The core experience centers on navigating a confined environment and engaging in combat.

Setting and Atmosphere

The entirety of the gameplay takes place on a single, custom-designed map. This map is themed as a demon-infested airship. The design of this environment is notably cramped and claustrophobic, a characteristic that significantly influences the player's interaction with the game space and its inhabitants.

Gameplay Mechanics and Features

As a shooter mod, the primary gameplay loop involves combat against a variety of demonic enemies. The defining feature of this mod is its highly restrictive and enclosed map design. This environmental constraint limits player maneuverability, demanding a focus on tactical positioning and immediate threat assessment. Players must contend with close-quarters engagements due to the narrow corridors and limited open areas.

What is the primary appeal of this mod?

The primary appeal of this mod lies in its intense, close-quarters combat within a uniquely confined setting. For players seeking a shooter experience where environmental limitations are a key factor, this mod offers a concentrated dose of action and tension.

What kind of experience can players expect?

Players can expect a challenging and atmospheric encounter. The airship setting, combined with the presence of demons and the restrictive map layout, creates a distinct mood. The cramped nature of the map ensures constant engagement, with limited opportunities for evasion from immediate threats.
