。
Even considering everything, it's designed so you just can't win.
Literal
Everything [object-を] considering [even-ても] as-expected cannot-win specification [state-になっています].
A gaming or competition context. 仕様になっている ('it's in the state of being a specification / it's designed that way') uses ~になっている to express an established design state. やはり ('as expected / after all') reinforces that the conclusion holds despite the effort. 勝てない is the negative potential of 勝つ — 'can't win.' The ても ('even if / even doing') concedes the effort (considering everything) while asserting the futile outcome.
