If you try to capture a Siren with that → good luck. The paralyzing state of an enemy is shown in green numbers like “6/140”. You have to keep the siren alive until the numbers grow over the stamina level of the creature. “142/140” then the siren would be caputred alive. If the Siren is dead before paralyzed: it is dead.
Until then the Siren is full alive it can do bad things to your team… but the more you paralyze it the less action points it will have.
Best way is to team up with Synedrion faction or steal from them. You will get weapons from them that are way more useful.
To your starting question: I have about 250 hours in the game. 100 of them in the actual game. I caputred a Scylla and a Siren ages ago. And still there is no end.
I think we might do things wrong. For me I defend every haven possible and clear out any infestation (playing Festering Skyes)
Playing on “Veteran” I have no clue why the Pandorans develop such hard shells and armor. It is almost impossible to win and it feels very hard for “Veteran”. I guess I would have no chance on higher difficulties.
Playing one Mission takes about an hour. And I have several missions a “game day”.
I don’t mind if it is a long game… I want to develop all tech, try out all weapons and build everything.
But I don’t think I will start a second game fast
I think the game is “Super extra long long war” mode.
