SAS: Zombie Assault 4 Mod is a top-down, twin-stick shooter developed by Ninja Kiwi. The game places players in a post-apocalyptic setting where they must clear zones overrun by infected zombies. Players manage a team of operatives, equip and upgrade a wide arsenal of weapons and gear, and complete missions across various maps. This mod APK is targeted at players who want to bypass the game's primary progression grind for gear and character upgrades.
What This Mod Unlocks
- Unlimited Money: The primary in-game currency (credits) is set to an infinite value. This does not decrease when spending on weapon purchases, character upgrades, or item repairs.
- Unlocked Premium Features: All gear and weapons that are typically locked behind premium currency or high-level progression are available for purchase with the unlimited credits.
- Ads Disabled: All interstitial and rewarded video advertisements are removed. The game experience is uninterrupted by ad breaks.
The mod functions by patching the client-side currency validation checks. Spending credits does not trigger a server sync for deduction in this modified version.
Activation Note
The mod features are active immediately upon launching SAS: Zombie Assault 4 Mod. There is no separate mod menu to enable. The unlimited money is reflected in the top-right currency display, which will show a fixed, high number.
This mod for SAS: Zombie Assault 4 Mod requires Android 5.0 or higher. The installation requires approximately 160 MB of free storage. Root access is not required.
Installation follows the standard sideload process for modified APK files.
- Download the modded SAS: Zombie Assault 4 Mod APK file.

- Launch the game after installation completes; do not run the original version simultaneously.
Known edge cases exist. The unlimited money is client-side only. Any server-validated transactions, such as purchasing certain special event items, may fail or revert. Progress is saved locally; clearing the app data will reset your mission progress and inventory, though the unlimited money will remain. Using this mod in any online co-operative or PvP mode carries a high risk of account flagging or ban, as the server may detect abnormal currency values.
