I just went through day 28 horde and survived using something similar to Jawoodles idea, ramp with a small tunnel at the end filled with traps. My tunnel is 3 wide, 5 long, and 3 high. 2 blade traps on each side inside for a total of 4 inside the tunnel. I wired electric fence through 4 of the 5 blocks long. Then set up one shotgun turret at each end of the tunnel, Shoot em up as they enter and before they get a chance to even leave lol. The blade traps on their own do not last very long, the Z's have this urge to destroy them immediately as i found out on day 21 horde. The combination of the electric fence and blade traps is pretty intense however. Blade traps do a ton of damage, as the basic Z's will die as soon as they run into the blades, and it doesnt take much longer for even irradiated ones to fall to their power..... they just dont have a lot of durability. Thats why i had the idea to run the electric fence through the tunnel, the zap stops them from going straight for the blade and gives the blades a chance to do what theyre intended to do. I didnt even have to turn the turrets on and i was still able to get a good amount of experience using an SMG to kill them as they were hitting the electric fence. I think im going to put one of these tunnels up on every side of the horde base and tweak each one a little to make them unique.... using blade traps and electric fence of course
ill try to get a screenshot of it this weekend and post it in this thread
