In some stages, you'll come across cloaking power-ups. Their very presence means that you'll need to use them at some point on your way to the goal, so adopt your strategy to include cloaking. Keep in mind that once you activate your cloaking ability, it lasts for only one movement. Then you'll be visible once again, so make sure that you make the most of your invisibility while it lasts.
Direct Is Bad
As you move around the facility, you'll encounter a lot of guards. If you try to take them on directly, that probably won't end well. Instead, try to enter their space from the side or from the rear. That will prevent the guards from becoming alert, and they'll be much easier to eliminate.
Hack turrets
Turrets are a minimal risk, you cannot afford to ignore them. They fire straight in a certain direction, and you'll have to discover a way to shield yourself or get rid of the danger. Armored guards can work as a moving shield (if possible, trap them in a red hex so you can depend on that security). In other cases, you can hack turrets so that they secure your enemies instead of concentrating on you.
Moves Count
You can complete stages by using numerous moves, and wasted turns won't cause you to lose. However, they will count against you. When you start a new level, check the move limit and try to take optimal paths so that you can stay within it and clear the game with 100% without having to repeat stages.
Turret Avoidance
Although turrets are a limited hazard, you can't afford to ignore them. They fire directly in a particular direction, and you'll need to find a way to shield yourself or eliminate the threat. Armored guards can serve as a moving shield (if possible, trap them in a red hex so you can count on that protection). In other cases, you can hack turrets so that they take out your enemies rather than focusing on you.

Always attack guards from the side or from the rear not only it will prevent them from becoming alert but it will be easier for you to take them out as well.
Cloak yourself when a stage requires it but keep in mind cloaking activity last only for one full turn.
