It seems that unless you play objective specialist and hog all the defuses/repairs/plants you really dont get any obj xp.
Ofcourse EV escort maps are a different when you can escort and/or damage it.
Dirty Bomb doesnt give you much or at all objective xp no matter how much you kill people trying to defuse your teams bomb or near the bomb for instance.
Just wanted to make this thread to congratulate and thanks the developers for creating this game.
I've seen Dirty Bomb quite a few times in the Steam F2P games list and I must admit that I've never even tried to download it back then due my poor free time.
So, I've just downloaded it (like 5-6 hours ago, if not less) and been playing non-stop since then.
DB's addictive, well built and the balance (of mercenaries and weapons) seems pretty correct.
I did not see any suggestion section though, maybe there's a reason for it ? (search function ? never heard of it)
Anyway. Hopefully this game will have a bright future.
