@NextWithoutFor Thanks for your feedback!! I'm happy more and more peolpe is testing the Beta version :)
Take a look at the quote below, with this strategy you will rock the first location. Before entering the mission, press X in the World Map to open the squad selection menu and select the heros as I mention:
There are tons of different strategies you can use. For example, in Royal Gardens I use to play with the following formation: (1) Oniki, (2) Krauser, (3) Dark_M and (4) Headshot (is the formation you can see in the last image of the initial post). I form a line with the first three and put Headshot behind Krauser. As Headshot has a wide action range, I cover Krauser and Oniki when they have low HP, and in the same way I cover Headshot from direct attacks. As Dark_M has a lot of defense, it can take care of itself alone, so I forget about it during the battle. The same strategy can be used replacing Krauser by Nightmare or Shadow, but in this particulary map I prefer Krauser because he reaches Trance state sooner (and triples his attack!!!) so I can use him during his Trance to beat the Evil (purple) Onikis. Take note that each mission takes a different approach so maybe this formation is not the best to use in other locations. Only the practice will allow you to know what heros you must select in each mission!!
Along with Royal Gardens there are two other initial missions if you want to test them: "Secret Cave" and "Imperial Ship". You can "navigate to them" by pressing the left/right cursor in the Wold Map. After reaching +40,000 points among the three initial missions you will unlock two more missions. There are 8 missions in total (I will create new begginer missions in future releases).
Keep me updated of your progress please!
