I have done all, include extra content. Challenge Extrema for need 50k, was most hard because every I hit then got wrong tap or double crouch instead ultrabatclaw and aiming instead fire batarang fast, those button I got problem. However I got last gold medal to complete 100% then unlock 2 achievement. I'd like to buy batman Arkham City, worse more point but more awesome gadget maybe fixed issued wrong button. Idk who is next game, maybe DMC4 that I left unfinished bloody palace to reach the top then some locked achievement including last 2 annoy achievement. 5 achievement left. Or looking Resident Evil 5 Gold Edition to finish in professional chapter and all dlc chapter. More than 15 achievement left.
