+This species is meant to be used both as a base for Event species and possible future per-round RNG'd species, hence the proc var-ization in some places.

+
+	icobase and deform				Set both to the same thing, unless you have special deformed sprites.
+	mobtemplate						The blank bounding box used by your species.
+	mob_size						The size class of the species. 20 is human.
+	show_ssd						What is shown when they're SSD?
+	virus_immune					Immune to viruses? 1/0
+	short_sighted					Permanent weldervision. 1/0
+	blood_volume					Initial blood volume.
+	bloodloss_rate					Multiplier for how fast a species bleeds out. Higher = Faster
+	hunger_factor					Multiplier for hunger.
+	active_regen_mult				Multiplier for 'Regenerate' power speed, in human_powers.dm
+
+	scream_verb						The text descriptor of the scream. Default screams.
+	male_scream_sound				Sound played when a male *scream s.
+	female_scream_sound				Sound played when a female *scream s.
+	male_cough_sounds				List of cough sounds for males.
+	female_cough_sounds				List of cough sounds for females.
+	male_sneeze_sound				Sound played when a male *sneeze s..
+	female_sneeze_sound				Sound played when a female *sneeze s.
+
+	speech_sounds					A list of sounds used randomly when the species talks.
+	speech_chance					Percentile chance to do the above.
+
+	total_health					How much damage can they take before entering crit? Default 100.
+
+	brute_mod						Physical damage multiplier.
+	burn_mod						Burn damage multiplier.
+	oxy_mod							Oxyloss modifier
+	toxins_mod						Toxloss modifier
+	radiation_mod					Radiation modifier
+	flash_mod						Stun from blindness modifier.
+	sound_mod						Stun from sounds, I.E. flashbangs.
+	chemOD_mod						Damage modifier for overdose
+	siemens_coefficient				The lower, the thicker the skin and better the insulation.
+	darksight						Native darksight distance.
+
+	meat_type						The food given when they are turned into meat.
+	remains_type					The effect left behind when they are ashed.
+	death_sound						The sound played when they die.
+	death_message					The deathgasp.
+	knockout_message				The message when someone gets a lucky shot on the head.
+	cloning_modifier				The modifier given when they are by chance cloned.
+
+	Any 'heat' or 'pressure' vars.	Environmental survivability.
+
+	speech_bubble_appearance		Part of icon_state to use for speech bubbles when talking.	See talk.dmi for available icons.
+
+	slowdown						Passive movement speed malus (or boost, if negative)
+	move_trail						What effect marks are left when walking
+	has_floating_eyes				Whether the eyes can be shown above other icons
+	has_glowing_eyes				Whether the eyes are shown above all lighting
+	water_movement					How much faster or slower the species is in water
