Some time ago I had a somewhat…psychotic Character ; he invented a new game: Goon-Bowling.
The rules are simple: Find 10 survivors and put them into a triangle, like the pins at bowling. Then, grab whatever explosive [grenades for authentic feeling, rocket launcher, if it’s your first time <3 ] and try to ‘knock down’ as many survivors as you can, with as little explosives as possible. The distance between each pin is, for obvious reasons, dependent on the type of ‘bowling ball’ you’re using.
Another game he invented: Willhelm Death.
Rules: Find a Survivor [bonus points for finding one with the Name Walter] and put him on Guard, after you gave him an Apple. Then, go some tiles away, grab your crossbow [Willhelm tell was in fact a known Crossbowman, not an archer, not sure why he’s always depicted with a bow…] or whatever gun you have, and shoot at the Survivor until you think you hit the Apple!
Another variant of the game needs a bit more work, and it’s timebased: Find a place with Triffids and lure one of them to your Survivor. Then go on the opposite site, while the Survivor is most likely fighting, and shoot at the Triffid. You win if the Triffid dies before the Survivor…oh, to hell with it, you also win when the survivor dies!
He also had some fun with Traps. Put someone on guard, put several layers of traps around the person and then call to them, that they should follow you.
The last game, which he actually never played: Bomber-Domino.
Put a few survivors in a line [don’t forget to space them out evenly] and give them some explosives - incendiary, C4, dynamite, you name it. Then give the person at the end of the line an active explosive and watch.
