Undead Siege Mod is a strategy game that puts you in charge of a squad defending its last stronghold from repeated zombie attacks. You choose forces, arrange them for battle, and keep improving the squad as enemy waves become stronger.
The combat focus is on adjusting your plan to the arena and the pressure created by several zombies attacking at once. You must build a response that can hold the stronghold while preparing your units for later waves.
Plan a Squad for Each Battle
You command the army and mobilize its forces for combat. Different situations call for different arrangements, so squad building is tied directly to the enemies and conditions you face in the arena.
- Choose troops for different purposes, with each unit taking a separate role during battle.
- Arrange the army carefully by learning how its forces operate together.
- Use Backpack Strategy to prepare quick approaches and surprise attacks intended to defeat enemies in less time.
- Adapt when zombie waves damage the stronghold, since their threat continues until you fight and upgrade your squad.
Heroes, Weapons, and Machines
Your formation starts with smaller units and grows into a stronger squad for combat campaigns. You can unlock unique heroes with different strengths and abilities, then assign them to battles where they can carry out their roles.
Weapons can also be unlocked, merged, and upgraded. As levels rise, ordinary machines can become more dangerous fighting machines, with power sources described as three or five times stronger. Gathering soldiers quickly before launching a campaign helps prepare the full army to counterattack the zombies.
Recent Battle Updates
Main stages now include special events with different battle rewards. Supply Pods can offer Power Core boosts or Overclock Tech, with benefits as well as drawbacks.
The latest update adjusts main-stage difficulty and reduces elemental effect strength following community feedback. It also improves Gem Mining and trait transfer tips, adds Gem rarity and lock indicators, and fixes issues involving auto-battle formations, boost selection, repeated Gem merge reward pop-ups, and some unit attacks.

Mod Review
This build suits players who want to focus on arranging troops, merging weapons, and responding to stronger zombie waves. It may be less suitable for players uncomfortable with the collection of location, contact, device, installed-app, and performance data. Players following current main-stage balance changes should also check the build version, because the official update adjusted difficulty and elemental effects.
What the mod changes
This modified build is labeled Free Shopping and God Mode. Those are the changes identified for this build. The squad planning, hero unlocking, weapon merging, zombie attacks, and main-stage content remain the game systems presented here. The exact behavior of the two labels can vary with the build and platform.
Pros
- You can assign troops to separate roles, which makes squad composition part of each battle decision.
- Heroes, weapons, and fighting machines provide several progression paths while facing stronger zombie waves.
- Supply Pods present Power Core boosts or Overclock Tech, including stated benefits and drawbacks.
- Gem rarity and lock indicators can make Gem-related choices easier to read during progression.
Cons
- The game collects personal, location, device, installed-app, and performance-related data, which privacy-conscious players should consider.
- A build based on an earlier version may not include the latest difficulty, elemental-effect, and auto-battle fixes.
- The 537.5 MB file size and Android 7.0 minimum requirement can limit compatible devices.
Verdict
Install it if its Free Shopping and God Mode labels are the reason you want an alternative build alongside the squad strategy gameplay. Before installing, compare this build's version with 1.15.8, which includes the listed event, balance, Gem, and battle fixes.
