Playing this for 1st time and can't seem to figure out how blow that damn door open at the droid foundry point. It says to
pick up the sniper piece by pressing F but it vanishes before I get to it, then it keeps reminding me to acquire it. Tried to
get my troops to lay some explosives at the door but pressing F and pointing the cursor at them per some "walk-thru" tips
does nothing. Maybe my tactical settings are wrong, but crap I have it set on easy (no laughing 😈 please).

Someone care to help a middle-aged "gaming illiterate" fart get over this hump before he goes nuclear?
