i open the a side of the doors (the brains side)
Then i buy a couple of random weapons, and then when i get a good one camp until dogs come
now you should have plenty of points so at the beginning of the first dogs switch on the eletric barriers.
I do this for every round i possibly can
Now at about round 7-8 i make a crawler and link all the teleporters (i usually have enough)
Kill the crawler when i get back to the power room.
Use the barriers again
then by the end of this round i should have enough to pack a punch a weapon so either make a crawler or teleport to mainframe.
Rush back to the power and then switch on the barrier again but this time camp where you were camping (on the stairs) and if you get too crowded jump off the rails and tele to mainframe.

NOTE-i would reccomend juggernog for this stratagy just in case
I got to round 19 with this on solo, so it would work brill for multiplayer...but ive never tryed it

you like? lol

theres no need for dog camping spots its only noobs that can't survive dog rounds.. i'd say im thinking on camping in the underground tunnel as at first i thought they could come down the hole by themselves but they don't if you get a flamethrower watch the hole on the left side so they probly like really weak by the time they get there

Run and gun is the way to go, escepially for dogs

friel i understand what u mean m8 but the stairs strategy is basically the same but u dont hav to watch a window, and if u shoot the flame thrower out the window in my strategy they hav longer to burn. i hav tryed both m8 and i wud highly recommend it

I got to round 25 alone by not opening any portals but camp in the room before the bowie knife, i had monkeys so i threw once every round to kill a few, then every round turn the electric on thats the only way they come in. + wonder waff + browning

does anybody like mine then...rate out of ten

i just got to 18 solo just going to were the first box spawns getting sleight of hand, juggernaut a mg42, ppsh and using the electricity and not opening the door behind me
