Solarix

Here is a detailed description of Solarix Stealth A.I and its relation with the game-play mechanics:

Solarix is a stealth game, and you can either use "stealth-based combat" or you can even finish the game without firing a bullet but knocking everyone out or you can even finish the game without alerting anyone.

If you like stealth kills, explore for ammo, use your pistol carefully(=combat) and aim for headshots and move around...

If you want to knock out enemies, don't use your pistol, use your tazer, observe their patrol points and knock them out one by one...

If you want to create your own darkness, use your pistol on lights, not on enemies...

If you want to "ghost" the entire game that is also possible, but you'll have to keep an eye your light meter and environment all the time...

If you want to lure enemies around, use throwable objects, not any weapons...

If you are around monsters and get caught, use your pistol to defend yourself until you find some cover/hiding spot...

Further in the game, if you are bored of sneaking around, use your shotgun to blast enemies, but you have to explore around carefully to collect ammo first...
