Delta Touch [7 x Doom engines] is an Android launcher created by Open Touch Gaming, designed to run multiple classic Doom engine ports on mobile devices. The latest version 4.8 was updated in December 2022, and the app is available for purchase at $2.49 with occasional discounts. It supports engines such as GZDoom, LZDoom, and Zandronum, allowing players to enjoy a vast library of first-person shooter mods and total conversions.
Gameplay Overview
Delta Touch acts as a unified frontend for Doom source ports, letting you load custom WADs, IWADs, and mod files directly from your device storage. The core gameplay remains faithful to the original fast-paced shooting and maze-like level structures, but the engine choice influences visual effects, weapon behavior, and map compatibility. Progression is tied to the mod or campaign you select, with many community creations offering dozens of hours of content.
Controls & Customization
Touchscreen controls are fully customizable, with on-screen buttons, virtual joysticks, and gesture support that mimic a mouse and keyboard setup. Bluetooth controllers and keyboard/mouse peripherals are also supported, giving you console-like precision or a classic desktop feel. You can adjust sensitivity, button layouts, and even assign macros for complex actions like weapon switching and strafing.
Visuals & Performance
Each engine brings its own rendering style, from the pixelated retro look of Chocolate Doom to the modern dynamic lighting and shadows of GZDoom. Delta Touch provides quick switching between engines, resolution scaling, and frame rate limits to balance visual fidelity with device performance. Offline play is fully supported, so you can dive into campaigns without an internet connection after downloading the necessary files.
The app also features a built-in file manager for organizing your mod collection and a downloader for accessing popular WAD repositories. Regular updates from the developer keep compatibility fresh with new Android versions and engine releases, ensuring long-term replay value for both casual players and modding enthusiasts.
