Culling Blade. If you could, add Foundary in the backround. It just feels right.

The Hottest Tamale

Model: http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2505

"Beans have never been so deadly..."

(+) On consumption:

• +75% Speed increase for 15 seconds
  
• +750 maximum health
  
• Instantly fills health and ammo to max

(!) EVERYONE (Yes, even you) in a small radius (256hu) is ignited upon consumption

(!) Max health becomes overheal when effects wear off.

(-) Put in the "Humiliation" stance during the effects duration

(-) Take Mini-crits during effect's duration

(-) 35 second recharge rate

引用自 Commander Mameshiba：

Can't see me (Spy Watch/PDA)

(+) +100% cloak/decloak rate
(+) Explosive Backstab
(+) On Backstab : Loud theme plays (John Cena's theme)

(!) On Disguise: Become John Cena (Modified Saxton Hale)
(!) Communism (Unusual Effect: Hammer and Sickle)

(-) Instant death on Backstab

I re-did some stats, so it would run/work better in-game. Source/Sourcemod isn't the best engine.

引用自 just this guy, you know?：

Hyper Trumpet Mk MMXV (Soldier secondary)

(+) On death 100% of your stored Charge is retained
(+) Gain 25% charge on death
(+) upon use, you and players around you gain MegaBuff for 10 seconds (including enemy players)

(!) MegaBuffs gives the effect of the Concheror, Buff Banner, and Battalion's Backup all at once

(-) No charge gained from attacking

I heavily nerfed it, but I think it's much better. Besides, with your old "Noclip for nearby players", people could get stuck.

The Extremely Loud Clap
Heavy Melee, normal fists model

(!) Attacking at any time will stun ALL players in a large radius for 1/2 of a second. (Equal to Sentry range)
(-) -100% damage dealt
(-) You are affected as well

EXAMPLE:

The Deuce Revver
Model: http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=74772074
"Revved up like a Chevy to the levee and it's gone to far."

(!) Rev up audio is randomly selected, looping chorus from one of the following songs

• American Pie, by Don McLean
  
• Rich Girl, by Hall and Oats
  
• Blinded by the Light, by Manfred Mann

(+) Invulnerable while spun up
(-) -100% damage dealt

Here you can post Balances, new weapons, or heck, even maps to play with during April First (and maybe a few days after?) Remember, Don't go OP if you can help it, just get silly.

EDIT Jan 15 2017 : I'm floored that people are still posting on this discussion. Thank you all so much for keeping this alive for so long.
