Bohemia Interactive’s Arma series remain almost uncontested as the games to own if the idea of realistic infantry combat tickles your fancy. The only barriers to entry have really been your willingness to deal with a game that prioritises realism over entertainment, the need for a relatively powerful PC, and the not-insignificant cost of the game itself. The Humble Arma 2018 Bundle fixes a third of those, offering everything in the series to date (minus the latest wave of DLC) for $20.
