that game truly is horrible. i remember seeing it at a local arcade when i was younger and thought it would be fun...boy was i wrong. i got my head chopped off about 4 seconds into the first round...and my experience went down hill from there.
as a side note, this evening, i was playing around on my mame cabinet with my 2 year old(he stands on a chair)..i left the room to get a drink and came back and he had switched to a different game list in mala and launched Blood Storm, which is the equally horrible sequel to Time Killers..i played a few rounds against him, cut off his arms, then we both quickly lost interest.
to get back on topic, i say if you got a good cabinet for a good price, then all is good..even if it is time killers. make sure you post some pics of the cabinet when you get it.
