Why the surprise at using TIC? you can kill more than one at a time: although they may not both be required for the recipe you still get points!
because I rarely see anyone using the TIC-80.
Of course I can, when 2 or more people are close together, but when far apart I have to wait for the bar to be full. I know in the game there is a recipe, but I have a very strong desire to kill someone (in this game of course) because the saw and blood effect in this game is very satisfying.
