We have rebooted and checked settings, we turned off , shooting at Prey only, every thing else is green box. What could be wrong? what else can I check? It used to work and then just stopped. I tried picking up the sentry guns and placing them back done but that did nothing.
like Escarli suggested, check the ammo levels. If there is ammo, try taking manual control of the weapons and fire them yourself to see if there are obstructions - maybe you built up too much around the guns and they have no clear line of fire.
The Zirax hate me with a passion for sure. It is a game error that I can't figure out how to fix. The problem is that they (the Zirax ) come into our bases and take the core out then we have to retake the base. Very frustrating . So this morning is just started working...
Without context this is a tough question. I don't play the storyline most of the time when I start a new game (just never complete the 1st steps) so I can jump back in at any time. Then I proceed to play "open world" and I do actions that give reputation points, so it may happen that when I encounter some factions their attitude will not be the same as when following the base game scenario from the start. So without more context, that is why I asked about the reputation.
If the sentry guns don't have the right angle to reach the enemies they will not attempt to fire at them. Then it depends on your device setup, sentry guns may not be in the same group like turrets in the device menu, so you need to look if they are activated when 'turrets and weapons' are activated, maybe you have a separate shortcut for them? Then you need to activate it and leave 'turrets and weapons' alone.
