Lol in all honesty, lab 2/4 isn't when it start getting hard, starts getting interesting at the end of lab 2 and u face the ai. From then on its a matter of how many cards and credits u have to complete maxing and proing not to mention the last couple of ai's cuz they ain't typical computer ai's that are easy to beat even with max pro.
