The main game menu. The odd thing under the magnifying glass is alien matter, when injected it portrays a world in which the Sentinel exists
The Sentinel world shows as a red/green grid in the window
There's the Sentinel. The spikes are in fact alien trees which block its view. They can be absorbed to gain energy but that reduces available cover
When the player builds a new tower and robot they can transfer control to it. The game automatically targets the old tower & robot so that they can be absorbed for their energy
Building a new block on a higher level. This is how the player advances across the landscape
When anything is absorbed it disappears in a do-nut shaped murky ring
When the Sentinel spots the player it absorbs their robot & tower. Game over
The Sentinel in all its glory
