bug fixes and hopefully clearer what's going on for playtest purposes
still just a custom gamemode test using existing maps for simplicity

-added underworld assets to hell to better convey to dead players that they are dead and in hell
-changed spawning-in-hell voiceline to better convey to dead players that they are dead and in hell (voicelines remain temporary for this alpha version)
-added hud message on spawn informing dead players they are dead and in hell, and giving them instructions on what to do now
-revised hud to try to make the above/below split clearer
-shrank former spawnroom areas in hell to reduce expectation that they act like spawnrooms
-added 1 second invulnerability to players spawning in hell to avoid spawnkilling
-reduced spread of spawn points in hell to avoid getting jumpscared by spawning players
-alive players who would teleport to hell now instead teleport to spawn in the overworld
-dead players who would teleport to the overwold nwo teleport to a spawnpoint in hell
-disabled building teleporters in hell to avoid cross-world teleporters triggering the above (the above are still needed to block eureka effect)
-souls should now vanish pre- and post-round to prevent resurrection timer from restarting during post-round and persisting into the next round
-hud now shows total minirounds won in post-round, and that score is no longer interrupted by a player dying in post-round
-now default 3 mini-rounds per round instead of five (6-9 minirounds per casual match instead of 10-15)
-slightly shortened resurrection timer to increase the mechanic's impact on the overall game
-added ten-second countdown voiceline ahead of control point enabling (voicelines remain temporary for this alpha version)
-replaced resurrection announcement and countdown with something more understandable (voicelines remain temporary for this alpha version)
-adjusted lava level in hell to make dropped ammopacks visible (and retrievable with well-placed explosions)
-built out more cubemaps, and hopefully fixed HDR lighting
