Hello there,
today i came up with a thought that psy amp must be some kind of weapon that is not working through walls.
Have a look:
this device can probably work
1. by fireing up
2. like a regular directed wapon
our psy soldiers never leave ranger, wich is somewhat wrong, making soldiers to see alien before they can psy attack will completely change out tactics. and its defenetly a setting wich do game harder.
And even more hardcore setting: loose control over an alien, who left a line of sight.
what do you think?
