Cancerous Beam

A new ability for Bopl Battle: Cancerous Beam. Charge up a radioactive beam and give your friends radiation sickness. They mutate, grow tumors and die. Platforms it touches come alive and get sick, and everything it touches mutates.

Made by Poyraz Acarbaş, a modder from Turkey.

Contains cartoon body horror: tumors, slime, vomit and tentacles.

Charging and firing

• Hold the ability button to charge. Let go to fire.
• A short tap fires a thin, fast beam. A full charge (3 seconds) fires a thick beam that bounces more and splits.
• While you charge, a radioactive aura around you slows down nearby enemies (more the longer you charge).
• The beam isn't instant: it flies very fast as a glowing green bolt with rings around it, so it can be dodged.
• Your own beam can't hit you until it has bounced off something.
• Cooldown: 9 seconds.

Radiation sickness

• A player hit by the beam has 32 seconds to live. Every extra hit takes 8 seconds off.
• They mutate: they turn toxic green, tumors grow out of their body, they get bigger, they twitch and jump by themselves, and a Geiger counter clicks around them.
• A radiation timer shows up above their ability icons.
• In the last 8 seconds they slow down more and more, in the last 5 seconds they cough like crazy, and then they die. There is no escape.
• It's contagious. Stand next to a sick player for about 6.5 seconds and you catch it too (20 seconds for you).
• Toxic clouds, sick platforms and other radioactive things don't infect you instantly: they fill up a meter above your head. When it's full, you're sick. Get away in time and it slowly empties.
• A sick player's own bombs, mines, missiles, arrows and smoke come out radioactive.

Bouncing

• The beam bounces off water, like the other rays.
• A fully charged beam splits in two every time it bounces, like a dividing cell (up to 8 beams from one shot).
• Two beams from different shots that cross each other blow up in a huge green explosion and shoot out 8 small beams.
• Everything else stops the beam: it sinks into the platform and the platform gets sick.

Sick platforms

A platform hit by the beam comes alive for 12 seconds:

• It breathes like a demon and you can hear it, and its heart beats: the whole platform swells on every beat and a red pulse spreads through it.
• Veins spread from the wound, pus bubbles pop on top and toxic slime drips from below.
• It's sticky (you walk at half speed on it) and standing on it fills up your radiation meter.
• Every few seconds something happens. There are 30 things it can do:
  • Hiccup, cough (pushes you away), sneeze (blows you off), scream (stuns you), sweat toxic drops, vomit (you slide off).
  • Grow a radioactive boil that swells up and spits small beams at the nearest player.
  • Open a mouth with teeth that swallows a player and spits them out.
  • Grow tentacles, spikes, legs (walks away and back), wings (flies up), roots (a bridge to another platform).
  • Clone itself, burst into pieces that come back together, melt, inflate like a balloon and spin away when the air comes out, morph into a tall shape, flip upside down, spin, jump, shake in a quake (you can't jump), sleep and wake up screaming.
  • Become a magnet that sucks everything in with one deep breath, turn invisible, become a ghost you fall through, teleport, become extra sticky, a racing heartbeat that bounces you up, and lay eggs that hatch into little radioactive critters.
• Ice maps: the icy platforms there aren't frozen, they get sick like any other platform.

Everything it touches mutates

The beam flies through items and turns them radioactive:

• Grenade: a dirty bomb. It melts a glowing Chernobyl crater into the nearest platform.
• Smoke bomb: the smoke turns toxic green. Stay in it for 3 seconds and you're sick.
• Mine: leaks radiation around it, and when it explodes it splits into two smaller radioactive mines.
• Missile: a reactor module. It heats up and speeds up while it flies. If it overheats or hits something: nuclear explosion, a shockwave, a mushroom cloud and radioactive rain.
• Arrow: a bigger, glowing radioactive arrow that melts its way through platforms with acid. The faster you shoot it, the faster it drills. Rockets and bombs fit through the tunnel it leaves.
• Tesla: the lines turn green and don't kill anymore, they fill your radiation meter instead, and a ball lightning runs along them and stuns whoever it touches.
• Black hole: it swells for 9 seconds with a siren and a countdown, collapses, and explodes as a SUPERNOVA that kills everyone on the map. Only a shield, being frozen or hiding inside a rock saves you. It leaves a radioactive nebula.
• White hole: it wakes up and grows tentacles.
• Spike: grows tentacles that grab people, lift them up, slam them into the ground twice and throw them toward the water or the edge. Mash jump to break free. They also whip people and throw grabbed bombs back at you.
• Muscle man boulder: becomes a comet with a rocket on its back.
• Rocket engine: becomes a fidget spinner that spins its platform like crazy.
• Rock: someone who turned into a rock splits into two rocks, like a dividing cell. The second rock crushes enemies just like the real one. When the rock ends, it flies back and they merge again. The rock protects them from the radiation.
• Space maps: the metal space junk goes into a nuclear meltdown and explodes.

With Freeze Ray Plus

Cancerous Beam works on its own, but it also works together with Freeze Ray Plus:

• The beam bounces off anything frozen (frozen platforms, ice cubes, icicles, ice bridges, frozen water) and gets stronger: 1.5x for one layer of ice, more for thicker ice. It gets thicker, bigger and brighter, and leaves a glowing radioactive trail.
• Being frozen pauses your radiation timer.

It also works next to Seppuku.

Online play

All of the mod's game logic runs inside the game's own simulation, so it stays in sync online. Everyone in the lobby should have the same mods and versions installed.

Notes

• The ability icon can be replaced: put your own CancerousBeam.png (340 x 292 works best) into the mod's icons folder.
• The sounds can be replaced too: put your own 16-bit WAV files with the same file names into the mod's sounds folder (kanser_*.wav). Sounds that have no file are made by the mod itself and can be replaced the same way.
