First, there were zombies - then came THE UNSEEN. A new virus not only makes the undead more biting, but invisible as well. UNSEEN AR is a unique arcade-style survival simulator. Rather than battling zombies in some abstract CG arena, you’ll fight them at home or work or even in the bathroom. Boost your skills in the free training area and get ready for THE UNSEEN. Via in-app purchase, you can release the invisible zombie horde to get the full experience. With a variety of weapons, it's for you to take on the faceless hordes and capture your best moments on photo and video to impress your friends. This is what AR was made for… and more. FEATURES: ► Built-in video and photo features to capture your gameplay ► Unique one-touch controls - tap-to-shoot, tap-and-hold to focus-shoot and drag-swipe to select a weapon ► Do it your way - Choose your Power Up’s wisely or dare to face a Challenge. ► Share your success - Record your gameplay with ReplayKit and share it with your friends. ► Choose your favorite weapon - Baseball bat, Pistol, Shotgun & grenades will come with different damages, ranges and availabilities. Train to find your Excalibur. REQUIREMENTS: This game requires an ARKit compatible device and access to the camera.

Verdict

The call

The clearest difference is rating: Stack AR at 3.8 against Unseen AR's 3.0. Stack AR also leads on ratings volume (2.1K vs 8) and review sentiment (32% vs 19%). Unseen AR's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 4 months). On price, in-app purchases, monetization model and device support there is nothing between them.
