the whole play with a buddy but buddy doesn't get any really good rewards and helps make your job easier reminds me of Dawn of War 2.....in the first part your buddy would take control of half of your squad (2 units) and be able to upgrade and equip them as he/she sees fit, but thats about it no reward for them and no xp, in the first expansion however i think they added achievements for helping out a friend so something to look forward to (i dont know what else is given because i mainly soloed it)...I also don't know about the most recent expansion, but possibly same deal, help a buddy out beat levels and don't gain anything but achievements out of it for beating so many levels as second player.....again I dont know what other benefits chaos rising and retribution give....but the whole "second player is just a support player to help make your job easier" reminded me of dawn of war 2 because basically the same thing happened there....might it possibly be a growing trend?
