HURRAH!! A CHAINSAW AT LAST!! EAT MY SPINNING BLADE OF ZOMBIE GRINDING!!
Ahem...anyways...a Chainsaw is a cool weapon but it attracts a SHITLOAD of aggro. I recommend carrying around a more silent melee when you bring along a chainsaw...because it's a bad idea to piss off or greatly annoy a boss/semi-boss/special. First Chainsaw, Dilmar PS, is at 50 melee and 30 strength (If you're too lazy to look it up yourself).
A Kris (Blade) and Dilmar (Chainsaw) combination is handy, as the Dilmar draws aggro but is good for exp grinding, and the Kris for when you want to avoid all that zombie bullcrap, 'cause when you get them going it's quite hard to stop. Be sure to bring along a ranged weapon, 'cause those new zombies can one-hit-kill you if you're in the 'serious' condition.
Trust me. Those new zombies hurt. I already suffered a nasty death three times due to underestimating those Tendril freaks (And a fourth from a Bone, those are bloody tanks). Avoid when possible, and if you do want to take one, DO NOT USE A MELEE AGAINST A TENDRIL. You can dodge a Bone easy if there aren't many zombies around and you're agile, but against a Tendril you're asking for a funeral.
Tendrils are rather easy to spot, and you need new glasses if you can't see a Bone once it's on screen (Unless it's out of your cam view, then I won't blame you for getting mauled.)
