Progression

System Design
The progression system was designed in such a way that experience points cannot be farmed easily through events such as destroying buildings, which do not award experience. The system only awards players through their contributions than "farmed" activities.

The progression system is mainly inspired by 2 existing leveling systems around. The first 150 levels is inspired from the current Team Fortress 2's casual leveling system (before Pyro Update). It expands another 2,000 levels after the first 150 by prestiging which is inspired from Overwatch's non-competitive leveling system.

Experience Points (XP)
Experience Points are known as XP, in short. Experience points can gained by playing on any server on the network. The amount of experience earned is determined by a variety of factors. The experience points will be awarded immediately when the event is detected to occur.

[Weekly Event] Double XP Fridays
Double XP Fridays is a special weekly automated-global event that occurs on every Friday. Players who play during the event will gain twice the experience points awarded to them.

[Bonus] Server Seeding
A server seeding event activates when a server has less than 6 players (or less than 4 players in Mann vs Machine or Machine Attacks). This event is activated to award players who seed the server.

Seeding is where one joins an empty server and attract other players to join. A player is more likely to join a server with someone in it rather than joining an empty one.

Level Tiers
Each level tier consists a range of levels. The number of levels in each tier is fixed at 25 levels per tier for the first 150 levels and increased to 150 levels per tier after prestige.

As you level up to a higher tier, the experience points required per level increases, making it harder to level up.

Prestige
Prestige is where one reaches the maximum level of 150 and enters into the prestige tiers. The prestige realm is divided into 4 tiers, Bronze, Silver, Gold and Platinum.

The prestige realm is fixed at 7,000 experience points per level.

XP Table
There is no level cap set for the leveling system, however the tier stops upgrading at level 2151. Players can level up indefinitely.

Patch Changes
