Cash is the currency used to aquire additional Classes and upgrades. It is obtained by participating in matches and awarded at the end of the round.
Cash rewards for matches[]
After an update equalizing rewards for all game modes, matches give the same payout regardless of map. A maximum of 100 cash is awarded for a victory, 50 for a tie, and 25 for a loss.
The later you join in a running match, the less cash you will receive upon completion of the round.
Historically, the rewards for matches varied by game mode.
After the release of training arena
Training arena: 50 cash upon victory
Shuttle bay: 100 cash upon victory
Moon base: 150 cash upon victory,
With the graphics update, the control point scramble mode was introduced to training arena, this gave the same reward as moon base (150 cash)
After the release of space station
All maps now award up to one hundred cash upon victory.
Before the removal of the Lab, cash could be used to purchase a variety of temporary boosts which had effects comparable with upgrades, though a bit stronger.
Formerly, it was possible to use 50 cash to respawn instantly instead of waiting for the team respawn timer to reach 0, though this was considered to be 'pay-to-win' by some, and was removed.
