* Flying Guillotine × Sandman
Now, all of you probably know this combo. If your aim is accurate, then this should be easy for you.

* Force-a-Nature × Crit-a-Cola
Did you know that with the Force-a-Nature's triple jump that speed = height? It's true! While under the effects of the Crit-a-Cola, your speed will slightly be increased. Therefore, activating the triple jump will make you jump higher! Don't believe me? Try it out yourself!

* Baby Face's Blaster × BONK! Atomic Punch
Now, this combo is perfect for getting past the enemy line. You just need to fill up your Boost meater, then use the BONK! Atomic Punch to make your way through. Because of the effects, your Boost meater won't decrease. And if the enemy sees you, they won't be able to catch up to you.

* Rocket Jumper × Market Gardener
I don't have to explain it. You all know this combo.

* Cow Mangler 5000 × Buff Banner
This might just be a small bug, but even though the Cow Mangler 5000 can't be crit boosted, it can be mini-crit boosted.

With the extra clip size, the health per hit will be really useful.

* Phlogistinator × Scortch Shot

Because the Back Burner's airblast eats up a lot of ammo, use the Manmelter to distinguish your teammates.

The Degreaser is faster to pull out and to put away, so this is useful if you want crits.

This combo is tricky. You need to use the Sticky Jumper to gain hight, the Loose Cannon to gain speed, and the Ullapool Caber to finish them off.

Because the Scotsman's Skullcutter has random crits, the Tide Turner is the best choice.

Make them laugh, then kill them quickly.
