Korean developer Red Duck recently revealed the first trailer for its new mobile shooter, Alliance of Valiant Arms: Guns On Fire. There are currently 9 playable characters, and a variety of different modes, including story campaign mode, raid mode, survival mode, and more. 5 different gun types were announced, such as sniper rifle, sub-machine gun, shotgun, rifle, and machine gun.
As you can see from the debut game trailer, AVA: Guns On Fire allows each player to bring 3 characters into battle, switching between them whenever required (such as low HP or when certain skills are more effective). However, players can only choose 1 in co-op and challenge modes. Some RPG elements have been added, such as the skill tree system. Stay tuned for more updates!
