Nerf NOW!! is a gaming webcomic. Originally centering on the RED and BLU Teams' endless battle in Team Fortress 2, it later branched out to story arcs taking place in Left 4 Dead, Starcraft, or one-shot comics based on other games. The latter is now the comic's primary focus, featuring metagaming issues from whatever game the author thinks is most controversial at the time. What sets it apart from its rivals is its art, which is animesque, dangerously cute, and somewhat inappropriate for a scenario involving two factions trying to murder each other, as well as for the fact that the comic is quite capable of telling a story without any dialogue (though more recent arcs have been using more speech bubbles).
Art Evolution or Art Shift: The November 22nd 2011 comic had much more detailed shading than previous ones (and Engie-tan dressed like an actual Engineer for a change). It remains to be seen if this is permanent.
Also, "can't think of anything to draw" comics. Usually, these involve short conversations between the author and Engie-tan, or Engie-tan briefly taking over the comic.
Bound and Gagged: Blue Engi in an early arc. Fortunately, Pyro's knowledge of muffle speak allowed him to understand her.
Butt Monkey: The Sniper. Back during the Sniper VS Spy Update, there was a string of comics with the Spy being far superior to the Sniper. He then later pissed of a RED Demogirl, and... it ended badly.
In contrast, Sniper-Tan has been exempt from this treatment. As of late, however, she has her own problems to deal with.
Corner of Woe: This one. Can't really blame the Medic for it; over more or less the entire arc, things were going really, really badly for him. Good thing the enemy heavy was sympathetic.
Dating Catwoman: The Engie-tans from the opposite teams are pretty much together by now.
Deep Immersion Gaming: From kill reports, chat channels, and the fact that they occasionally change classes/games, the two teams are obviously in a video game, though their players are never shown.
I Warned You: When the Engies go out on a camping trip, BLU-Engie brings along her DS and extra batteries while RED brings "her spirit of adventure". When nature dumps a rainstorm on them, keeping them in their tent, BLU rubs it in when RED admits she's bored.
Kiss of the Vampire: Skyrim's Lydia is asked what Engie-tan should afflict herself with: lycanthropy or vampirism. Lydia suffers often from Video Game Cruelty Potentialand she knows that eventually Engie-tan is going to eat her. So she chooses sensual neck nibbling over being ripped into pieces.
Not What It Looks Like: Jo spills some ink on the floor and the Lusty Argonian Maid slips on it, falling on him; Engie comes in and it looks like the two are making out. The maid says this, but Engie sees the ink on the floor and deduces what really happened. Jo would rather people think they were making out, and tells Engie that's not what happened.
The Heavy after joining a team of "babies". Has shown elements of being a Papa Wolf as well.
The old man from the "Noob" arc.
Parody of Evolution: This strip depicts an Engineer hunched over a turret, a somewhat short Pyro, a normal-size Soldier, and a Spy with a visible paper mask.
Rescue Romance: The very first arc. And it doesn't work out for Pyro.
Reverse Cerebus Syndrome: Started out as a series of story-line based dramedies before evolving into one-off comedy strips. Jo still does story arcs, but they tend to be much shorter and continuity has become harder to come by.
Mostly because, as the most recent (and, as it happened, "last") arc proved, viewers prefer the stand-alone strips.
