I usually use my time machine and watch the battle a week ahead watching their every move and then go back and use that data to my advantage. Some would say that's cheating but I say it is just very convenient tool to use on the enemy, I have also been known to put tracking devices on them, yeah its dirty but its a useful tool to use against them as well. If only I could use a host poison to make them weaker and REALLY easy to fight, but alas they are immune to poison, probably because they are not really living creatures to begin with. I thought of just calling in some alien backup and destroying the planet, that'll get 'em for sure it will, those buggers. Any of those bastards get by me it will be a miracle, or maybe a glitch in my time machine data, or a glitch in the matrix in general.
Seriously though, only day 28 and I got my ass kicked. I went through 500 rounds of 7.62 and I had spiders jumping on to my platform over my iron bar guard rail, seems they have greater range in A18. So without my junk turrets and my lone SMG turret my horde defense base would be rubble.
