Thanks.
I just tested ''SteamRoller'' and i'm not suggesting you using that as your enemies strategy
Your enemy will start building troops so fast that I couldn't even finish 2nd War Factory I was already defeated.
Oh, that sounds tough! Set it to easy and use a trainer, you'll be able to defeat the AI really fast. I think a guerilla player is one that uses sabotage and special forces mainly (like the Shadow teams).
