GAMEPLAY MECHANICS
Acceleration
"Sonic" and survivors share the same average starting runspeed, however as they continue running they grow faster, with each survivor and killer having different maximum runspeeds.
Hazards
As shown, each map has its own set of hazards, all of them are different depending on the map, but killers are resistant to them, with "Sonic" (and Metal Sonic) being able to run through them, only taking small chip damage.
Rings
HP is measured through rings, with each survivor starting with 100. "Sonic" starts with 250, but some killers have damage resistance which effectively makes that amount higher. Groups of rings and ring monitors spawn naturally around the map, with individual rings giving 1 ring (duh) and ring monitors giving 15 rings.
Extra Lives
Around the map are 3 randomly spawned and well-hidden extra life monitors with a random survivors face on them. These monitors can be broken by a survivor to revive them after death, or by "Sonic" to bring back the fallen friend... but not the same as they were. The Fallen, as they are called, act as minions that can be annoyances for survivors and provide in-chase support to the killer. They are slower and can be somewhat easily killed, but retain a few abilities that can make them a threat.
Invincibility Frames
After a survivor is hit, they are knocked back a considerable distance and their current velocity is stopped, afterwards the survivor flickers translucent for 4 seconds and is invincible to all damage, before becoming vulnerable again after this period.
Minute of the Inferno
The universe's faulty attempt to restart itself begins to fall apart once again after a few minutes, and the sky begins to tear as hazards worsen and a single gateway in the form of a portal ring opens. Survivors must run to the ring and escape within a minute, allowing them to avoid a worse-than-death fate in the Inferno's eternal fires.
