STREET FIGHTER X TEKKEN

If Mission 1 isn't doing it for you, try Mission 2. Just use the "Hardest difficulty" strategy.

Select Zangief, get close to your opponent and pound that LB button until he's KO'd.

Done!

To earn this achievement, you have to clear at least one mission in the Mission mode.

On the main menu, highlight Challenges and select that option. On the list should be Missions. Highlight that option and select it.

Next, you'll come across a slew of missions for you to undertake. To make this achievement easier to earn, select the first mission, which requires you to beat your opponents with normal moves only. Select your team and enter the battle.

From there, just pummel them three-hit chain combos. If you had done the tutorial, you'll know what I mean. If not, just hit LP->MP->HP high or low or LK->MK->HK high or low, as in either standing or crouching. You have at least sixty seconds to finish your opponent under those conditions, so quickly get to work and be on the aggressive constantly. Do this properly, one of them ends up being finished, and the achievement should unlock right then and there. To speed up the process, I used Ryu and Ken, since I know them pretty well by this point.

Have fun and good luck!
