About

Alien Observer

Features
Read full description

Your Home world is slowly dying. You are a young alien Observer Corps agent on your first deep assignment, sent to study a remarkably promising third planet the locals call Earth. Plot your orbits, scan, learn, and try to stay invisible. WHAT YOU DO Design transfer orbits and time your burns in an original orbital mechanic. Scan biomes, cities and oceans through alien eyes. Solve mini-games to calibrate sensors and stabilize anomalies. Make strategic calls. Manage antimatter, intel and samples. Upgrade your ship. Level up your Observer. Climb the Council ranks. File reports. Honor the Prime Directive: remain unseen. A blend of orbital strategy, RPG progression and resource management, with a healthy dose of dry humor about a bureaucratic alien civilization trying very hard to understand us. SUBSCRIPTION Annual Season Pass is an auto-renewable subscription, 1 year duration. Price is shown on the purchase screen before you confirm, in your local currency. The Season Pass unlocks Advanced Autopilot, two Data Storage licenses, the Chapter 2 expansion, the Generalist class, the Pets Pack with all four companions, and every DLC released during the year. All unlocked content is yours to keep permanently, even after the subscription ends. IN-APP PURCHASES Alien Observer is free to play. Optional one-time purchases include antimatter reactor refills, the Data Storage License, Advanced Autopilot, the Chapter 2 expansion, and animal companions (Laika, Ham, Cow, HAL9000), available individually or as a Pets Pack. These purchases never expire. ADS Optional rewarded video ads can be watched to earn small in-game rewards (a unit of antimatter, a skill point, raw data, or a reduction in Notoriety). Ads are never required to progress. The Annual Season Pass does not remove ads, since ad rewards remain useful regardless of subscription status — but Season Pass benefits make them far less necessary.

Verdict

The call

The clearest difference is ads: Ever Upgrade at none against Alien Observer's shown. Ever Upgrade also leads on iOS requirement (13.0 vs 17.6). Alien Observer's advantage is update cadence (every 3 weeks vs every 2 months). On price, in-app purchases and device support there is nothing between them.
