The Merc with a Mouth stars in his first solo game. It's a pretty standard beat'em up with a little bit of shooter and stealth mixed in. This game is pretty straight forward and for the most part the achievements are easily obtainable. If you miss anything during your playthrough, there's a chapter select to go back to any mission to get what you missed. That being said, the game is fun and hilarious, so sit back and enjoy it and mop up what you need to after you finish the game.
Play or normal (Veteran) or easy mode. During this playthrough you can knock out many of the achievements pretty easily. During this playthrough, upgrade your skills as much as possible. You can be fully upgraded after playthrough pretty easily. Guns are particularly useful for the hard mode playthrough, so try to make sure these are upgraded.
Hard mode (Ultra-Violence!). If you've upgraded your skills in your previous playthrough, this run isn't too difficult. Using your guns helps out a lot. The counter for the Pulse Rifle will kill many smaller enemies in 1 hit and also doesn't use ammo when countering. This basically replaced my melee in many spots. If you're having trouble, you can just keep teleporting forward and hitting check points. The enemies tend to eventually catch up to you and kill you, but by then you've hit a few check points and will reload at the closest one. This can speed up this playthrough a lot. If you're doing hard mode as your first playthrough, upgrades your guns as soon as you can and make sure to evade and counter as much as possible.
Play through the challenge mode getting gold on 5 of the maps, as well as the snagging the "Shields Up" and "Cole'd Blooded" achievements. Challenge mode isn't too difficult, so this shouldn't take too much time.
Use the chapter select to clean up any achievements you may have missed.
