In addition to Shell Shockers, one of the most interesting games I have ever played is called Deep.io. Developed by Matheus Valadares, this game is quite unique as it focuses on both strategy and action gameplay. In this game, players are placed on a vast battlefield where they must face other players in an attempt to destroy them while avoiding being destroyed themselves.
Like EvoWars.io, there are many different types of weapons that can be upgraded and used by the player to accomplish various tasks or simply just to wreak havoc on the opposing team.
There are 8 different modes, including FFA, Survival, 2 Teams, 4 Teams, Domination, Tag, Maze, and Sandbox. Each mode has unique gameplay. You can fight alone as playing Cuphead. It is possible to cooperate with other players to form a team and fight. You are free to choose one of eight game modes before coming to the official battles.
