At the Arena, when players choose "Deathmatch" or "Team Deathmatch" modes, they are allowed to bet.
Bid's maximum value depends on current level of a general that you want to use to participate in a particular battle.
There can be only one winner who gets everything.
After "Team Deathmatch" is over, the winner team's survivors share the prize equally.
Players do not need any minibots or credits to take part in the training combat.
When the battle is over, the Astro Lord is rewarded with all the resources collected during the battle.
