But it's doesn't. In mercenaries, you have freedom to choose your characters and your map, and some alternative costumes change the entirety of your weapon collection. You can even play multiplayer (in the later games) just to make it more fun. I don't want a mode made to speedrun...that's just...extremely boring. Especially when you're limited to playing the one character on their one specific map with no chance to change any of their weapon kit. The gameplay would get repetitive and stale real quick. Hell, I'm already done with playing The Fourth and Tofu Survivor because there's pretty much nothing to it besides "Avoid attacks, run to the other side of the map". Raid Mode is like an extended version of Mercenaries...but a little more complicated and has a lot more content.
