RTA stands for random tactical arena. This is the remake of the infamous heroes 5 map for quick multiplayer duels. Unfortunatelly, scripts don`t work in online mode so the map is playable only in Hotseat for now. Playing vs AI is also possible, but to do that start a Hotseat game vs Human and manually do all the things for the AI. When you meet the AI hero in the arena , arrange its troops and then set it to autocombat.(by Natalia)
