Tiers

The tier system is a system that upgrades zombies every 1.5 minutes to make rounds more intense during the duration of time. Each upgrade stacks with previous upgrades. There are 4 tiers since I believe timed rounds in R2D didn't go past 6 minutes. Correct me if I'm wrong so I can fix it.

Tier 1: +5 HP, +1 Walkspeed, +20 Energy, Increased Special Spawn Rate, Increased Armor Spawn Rate

Tier 2: +2-3 Damage, +5 Energy, +1 Walkspeed, Increased Special Spawn Rate, 2% off on zombie buying, Decreased Armor Rarity

Tier 3: +10 HP, + 5 Energy, Increased Special Spawn Rate, 5% off on zombie buying, Increased AI Zombies

Tier 4: +5 HP, +1 Damage, Increased Special Spawn Rate, Increased Brute Spawn Rate, +10% off on zombie buying, Increased AI Zombies
