Comments on The Sentinel for Android

★★★★★ Alex H44 · Sep 22, 2021
It's at least 35 years since I last played this game, and it's just as awesome as it was then. Gameplay at its best.
★★☆☆☆ Adrian Wood · Mar 28, 2021
OK, I may be misremembering the original, but I'm sure the Sentinel couldn't absorb your energy if it couldn't see you, but in this version you can be somewhere the Sentinel's view is defo blocked, and still get your energy drained. That, along with both turning speed and absorb/spawn animation being super slow, make the game basically impossible. (Also, does this company even have the rights to this game? I thought the rights were currently with SCE...)
★★☆☆☆ Jim Foronda · Jun 8, 2021
A good start of a remake of The Sentinel so far, but two issues currently make it unplayable, though: First, The Sentinel is *not* supposed to drain energy if the player can't be seen. There seems to be a glitch in that you can be drained even if The Sentinel is out of sight. Second, it really needs the ability to adjust or increase view movement sensitivity. On my phone, it requires *way* too many swipes to even rotate 90 degrees. If these two items can be addressed, it'll be great, I think.

Description by Horizons Aviation Ltd. Written by the developer, not by AppBrain. Click to read.
The Sentinel controls each landscape from high above. The aim of the game is to get your robot to a high enough viewpoint so you can defeat The Sentinel and conquer the landscape.

You start the game as a robot starting low down on the landscape. With a limited energy supply you can materalise new robots onto the landscape and then transfer control to them. Using blocks you can gain height for the new robots and with each transfer you can get higher up. Remember to absorb the old robots, blocks and even tree gain energy.

Once you are high enough to see the tile that The Sentinel is standing on, you will be able to absorb The Sentinel and take his place to win the level. You must manage your limited energy level by reabsorbing old blocks, robots and even trees.

The Sentinel will not make your task easy. He slowly rotates looking for energy to absorb. Once he spots you, his gaze will lock on and he will start draining energy from you. You must quickly transfer control to another robot or try a risky hperspace to a random new position.

Some levels will also have up to 5 Sentries. These act just like The Sentinel but are lower down the landscape. Energy absorbed by The Sentinel or the Sentries is redistributed to the landscape as new trees.
