I was pretty intrigued by Battlefield Heroes until I actually played it. I still like the aesthetic and humor, but I never felt compelled to drop money on it, so it only held my attention for a weekend. Despite this, mad scientists turn my legs to jelly, so I'm back to being intrigued. The Royals and Nationals will each get their own scientists, the Inventor and Dr. Doktor.
I may have to give the game another whirl, I love blowing soldiers up with science! Over the next three months there will be even more content added to the game, I'm hoping for Captain America personally.
