The answer before the background

Our recommendation

Alien Shooter TD PC has two official routes: the native paid Windows game on Steam, app 541230, and the free mobile edition delivered to compatible Windows systems through Google Play Games on PC. Steam lists Windows, 2 GB RAM, a 512 MB video card and 500 MB storage as minimums and includes achievements, Cloud, stats and leaderboards. The Google route remains package com.sigmateam.alienshooter.towerdefence with ads and in-app purchases. A ‘full version PC’ mirror is not needed, and ownership, saves and purchases are not promised to transfer between the two products.

Check the native build correctly

Steam lists Windows 7 SP1/8/10 historically, a Core 2 Duo T5200 or Athlon 64 X2 3600+ class processor, 2 GB RAM, 512 MB graphics and 500 MB storage. Steam client support now requires a newer supported Windows version, so use current Steam requirements rather than treating the old OS line as a recommendation.

The Google Play Games on PC route has Google's own compatibility checks. It can be useful when a player wants the mobile economy and account, but it should not be described as the native Steam binary.

Keep account and economy boundaries visible

  • Buy the Steam product on the account that should own the Windows license.
  • Use the intended Google account for the mobile package and its purchases.
  • Do not promise Coin, Mineral, weapon or save transfer between stores without a first-party transfer feature.
  • Use Steam file verification for the native build and Google Play repair/update controls for the mobile build.

Repair the edition you actually installed

For Steam, verify files, check Cloud state and temporarily remove external tools. For Google Play Games, confirm the package, Google account, service update and compatibility. An error in one edition does not prove the other license is included.

If the Steam product does not fit expectations, use the published refund process where eligible. If a mobile purchase is missing, use Google purchase/support records. Do not install a crack or mod as a bridge between accounts.

Common questions

Is there an official native PC version?

What is the other Windows route?

Google Play Games on PC distributes the Android app on compatible Windows systems under the Google account.

Do mobile purchases transfer to Steam?

No transfer is promised by the checked listings. Treat ownership and economy separately.

Use Steam for the native Windows product or Google Play Games on PC for the mobile edition; avoid mirrors.
