Allow me to hand you your first SF victory! My guy was severely injured (and therefore slow) after being shot the first time, and with turns beginning to run out I was left with no choice but to chance my diminished action points on the next shot being a miss...
More than happy to be your sparring-partner for some future missions should you be up for it.
Hmmm...I don't think there's another where one side knows the enemy's whereabouts at all times, but advanced mode allows both sides to "hear" units who are moving/shooting in nearby squares, and the alien in...well...Alien can hear the Nostromo crew members from considerably further away. And then there are alternative unit types who have other supernatural abilities: the angels, for example, have a Doctor Who thing going on (super-fast, deadly at first strike, indestructible, but can't move if in any enemy's line of sight), and the zombies, while slower, reanimate after a random number of turns. Happy to set something up if any of that sounds intriguing.
