Hills of Steel *tank* mod
=========================

Version **8.7.1** · Supercharge Mobile · `com.superplusgames.hosandroid`

Why this *mod* exists
---------------------

Hills of Steel is built around a long upgrade ladder. Coins unlock new tanks, gems buy permanent boosts, and the campaign expects hours of grinding before the Reaper or the Mammoth becomes a sensible pick. The mod build removes that economic friction so the gameplay is the focus: which chassis matches the terrain, when to time a homing rocket, where to flip into the air on a Moon Breaker ramp.

The official app on Google Play is a free download with rewarded ads and a paid IAP tier on top. Players in cost-restricted markets land in the same Play Store storefront as everyone else but face local-currency pricing that often makes the gem packs unworkable. The modded [APK](https://bestforandroid.com/apk/ "apps apk download") on this page treats the campaign and the tank roster as already-purchased content so the same physics engine plays the same way at every progression tier.

Note that this is a single-player and 1v1 / 2v2 local game core, not a competitive ladder with PvP matchmaking that would expose unfair upgrade gaps to other players. The mod’s perks change the local experience, not someone else’s match.



 ![Hills of Steel gameplay: physics-based tank battles on diverse terrain](https://bestforandroid.com/apk/wp-content/uploads/2026/05/hills-of-steel-screens.jpg) Hills of Steel in action: hand-drawn terrain, physics-driven chassis, multiple tank classes

What this *mod* offers
----------------------

- **Unlimited coins.**The currency that gates the tank roster and the chassis upgrades is treated as already-earned. Buy without grinding the campaign for hours.
- **Unlimited gems.**The premium currency that powers permanent stat boosts and crate unlocks behaves the same way. No IAP needed to access the gem-tier content.
- **All tanks unlocked.**Reaper, Mammoth, Cobra, Joker, Titan, Phoenix, Atlas, Siege, Kong, and the rest of the forty-plus roster are selectable from the garage on first launch.
- **Max-level upgrades.**Firepower, armor, speed, and special-weapon tiers ship at their ceiling so each tank performs the way the late-game build is meant to feel.
- **Ad-free play.**The interstitial ads between rounds and the rewarded-ad prompts at level fail are removed from the gameplay loop.
- **All game modes accessible.**Arcade, Versus, Winter War, MidSummer War, Desert Assault, Jungle Patrol, Moon Breaker, Mars Invader, and Boss Rush are available without progression locks.
