1. This game does not use matchmaking and THANK GOD it doesn't. Matchmaking sucks quantum singularity! It's better to have control of where you want to play not let the MM service do it for you and have you paired up with cheaters or laggy players.
2. You can do a search of joining a game lobby or make your own. You cannot join a game in progress
3. DO NOT play with people who are "level 256" cause they are using a hacked level and it can infect your profile too. Watch them scroll through their character list first and if you spot one, just leave. Other ways to see if they are using a hacked file are:
- They have over 1 hundred red healing potions (limit is 5)
- Their magic spells literally fill the whole screen
- Their melee damage is over 300 range. Very high.
- They have tons of health and almost will never die.
- Their inventory has items they cannot use (just icons)

4. Whatever you completed in SP will be transferred to MP so you can get help from ppl to continue the rest. Just be aware that if someone has levels completed further then you, you will get access to those levels if you wanted to skip ahead BUT you still need to finish every level to get credit for the achievement (finish the game) and to get a Silver Skull over the portrait of your character you finished the game with at the character select screen. If you're gonna skip ahead, try to remember where you left off.
