I’ve played a lot of solo private matches, especially on derailed and overgrowth, and it certainly helps to have good map knowledge. I’m familiar enough with the missions now that I know if they’ve chosen to spawn in a certain area which direction they are likely to go. If I’m unsure I’ll drop a motion detector in one path and head in other until I get a ping or spot them.
As far as reinforcements, yeah. I kinda know the locations but honestly? Unless the team is super strong and keeping me on my heels I’ll let them reinforce just to keep it interesting and maximize my fun. After waiting 15-20 minutes to play I like to keep the match long.
