Worlds of Chaos: Invasion is a single player, party based open-world tactical/action RPG with a strong emphasis on exploration and tactical combats. It has a deep combat system that will challenge you to your limits, and will make clever decisions count.
You build a party of 5 characters that are exactly what you want : no classes or choice restrictions. Creating good and balanced characters with the right stats, skills, equipments, items and spells combinations is what matters the most. In this game, a huge importance has been put on making every choice equal in power. What is important for a good party is not choosing the best skills, but an efficient combination of choices that work well together.
Battles are fast-paced, and you will need to take a lot of decisions, each of which will help you overcome the difficult foes that you encounter. Choosing which spell to use, when and how to use them, and the positionning of your warriors and choosing the right targets are what will bring you victory.
