It's a rather silly Summer holiday tradition that's (regrettably) existed for many years, anyway here's the premise.
It's Galaga (fast shoot rom) running on an old version of MAME32. Rules are simple, loss of life equates to a shot of nasty OP bourbon. No fighter captures are permitted, so no doubles for the challenging stages. We're about 12 or 13 in at the time this was captured so it's inelegant at best. We play on full size arcade hardware because it can handle the abuse.
Please, don't try this at home.
