ZHorde — Zombie Survival

Implemented 'Challenges' with different types that alter gameplay, with their own competitive leaderboards.
Implemented timers on each challenge from a player, if a player gets a faster time than the previous then they take their spot
Implemented a 'weekly reset' on challenges, every 7 days the leader boards wipe and start again
The 'Medic' and 'Hoarder' class cannot be used when attempting the 'Berserker' challenge.
Implemented a 'PRIZE' award that after the 7 day reset, the player to complete a challenge in the fasest time (the challenge is picked at random) will receive a premium store reward!
Reworked the 'Genocidist' class as it was way too strong in its current form, leaving no challenge for players
Fixed the wave HUD sometimes appearing after dying and being teleported back to spawn
Fixed /stuck not teleporting you back to spawn if you're already in the hub world
Implemented 4 new Achievements:

9.1. 'Dare Devil' - Survive two waves with less than 10% HP - 2000 XP
9.2. 'Untouchable' - Survive 5 minutes without taking damage once - 5000 XP
9.3. 'Sword? Don't Know the Guy' - Win a game without ever using a melee weapon - 3000 XP
9.4. 'Born to Challenge' - Complete 3 Challenges successfully - 3000 XP
Implemented the 'Matchmaking system' instead of going through portals, this encourages more team play and helping out newer players for veterans!
