Fast answer
The answer before the background
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.
Choose edition
Native Steam and mobile-on-PC are distinct
| Route | Commercial model | Identity |
|---|---|---|
| Steam | Paid Windows product | App 541230; Sigma Team Inc. |
| Google Play Games on PC | Mobile app with ads and IAP | com.sigmateam.alienshooter.towerdefence through Google. |
| APK emulator/mirror | Not needed for official access | No store provenance or support guarantee. |
| iPhone/iPad | Free with IAP | Apple app ID 1132242499; not a Windows license. |
Requirements
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.
Ownership
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.
Troubleshooting
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.
