on this orange map, the particle gun power 2 owned o..o no artifacts used either! i actually was not happy i summoned it on wave 4, so i kept using the mini power 8 for awhile until things were getting tough. so i figured the particles from alt fire would keep me healed from so many going around and hitting stuff. i outfitted it with +10 damage and 4 rages, which was all i could since i needed the infs and superspeed. i didn't even use a heal pu since i was trying to go for most damage so vamp would do its best.
i would like to thank all wands and nukes for killing everyone so i could have more monsters ^,,^ just kidding! anyways, yes, wave 18 all but two were out, so i hid in the upper part and spammed these things over and over and over..until i got bored and felt i needed something to end it faster. so i went for flak bombing over the edge for awhile..until i realized i had a mine layer. so i used that then. after all enemies were gone from my side, i reequiped particle and spammed them to the other side until everything was gone.
while i did not have any artifacts, someone was using super lucky or such, since i saw a double damage hanging around the map at least 1-2 times a wave. so yes, i did grab them for my 30 seconds of strength. they came in useful on wave 20, and baby, that wave was all mine...mostly. i did see someone else running around while the rest hid, and a nuke seemed to take out most everyone else hanging around in the hide spots above.
particle gun, no artifacts, and not even a super weapon. yes, not a full load of people, but this is still impressive nonetheless and another nonsuperweapon besides razor bomb that can racks up the damage points!
