Who needs a katana when I've got my trusty Fatknife with me?

This is a simple guide on how to use the sooo underrated Machete!
I used the machete on suicidal with level 5 zerker, so other perks may need different approaches, but I'm pretty sure they may do about the same stuff on lower difficulties!

So far I've been able to get to wave 10 (suicidal) dying 2 times (the last one being on wave 10, when we all died and lost), so it can't be that bad, right? ^^
First, what is the Fatknife capable of? In short, instakilling everything except Scrakes and Siren (and Patty, but who cares?

).
-
Clot: either a normal attack to the head or an alt-attack to the body for an instakill.
-
Stalker: alt or normal attack, makes no difference: instakill (you get instakill only with alt attack if you're not level 5 zerk though).
-
Crawler: just like the stalker, but pay more attention to these: strafe, let them jump and kill them when they land.
-
Gorefast: this one is a bit tricky to instakill, because whenever they get too close they won't get decapped by even alt attack: the trick is to get the right timing and strike a pair of moments before they get sticked to you with alt attack for instakill (either way it's usually 2 alt attacks).
-
Bloat: alt attack to the head: bloat explodes.
-
Siren: you are either fast and get her while she's chasing a teammate or you have to wait her behind a corner, then alt attack her 3-4 times.
-
Scrake: he can be stunned by alt attacks to the head, so keep hitting it until he bloody dies!
-
Fleshpound: like with any other weapon, wait for him to bow down for attacking and poppy head (tm) him!
-
Patriarch: never meleed Patty on suicidal, Xbow does the job right...
The Machete works better in open maps like KF-Farm or KF-DeathBasin (just like any other melee weapon, afterall); the best backup weapon to use is the Xbow for taking out pesky Sirens and Scrakes from afar (and Patty, but who cares?

): yes, the Xbow is the backup weapon for the Fatknife (expecially for non-zerkers) and not the opposite, remember!
Using this instead of the Katana is also good for conserving money (yes, you won't use them for buying a Katana later, but it's good for teammates, isn't it?

) because it costs just 100
