Bots

Bots are NPCs that one meets when doing Quick Matches (QM) and not finding real players at one's own Strength. Bots are (usually) met after 60 seconds of waiting. But if you lose a QM, you're immediately pit against another bot with no wait.
Bots copy other players builds, rotation (order of their actions on the action track) and swaps.
When fighting bots, the battle background shows a hilly desert, while fighting real players it shows stone pillars and shapes of buildings.
If a player beats a bot, the system will usually match the player with a different bot in the next match, trying to find a build that beats the player's setup, i.e. a counter.
Winning a match, i.e. beating a bot or a real player gives 16 XP & 250 Metal.
Losing gives 6 XP and 125 metal. But the metal only for the first XX (10?) consecutive losses each day to prevent intentional losing just to pile up metal. Loss counter is reset after a win and metal will be awarded for the next XX (10?) consecutive losses before the next win.
