Gunmaster 2d extreme warfare saga is a game that has a mechanic where you must master movement and shooting at the same time. i found the physics sometimes don't cooperate which makes the chaos even more fun.
Clicking fast and moving around is how you start the action. You can switch weapons easily to deal with the overwhelming enemies. The controls feel wonky during hectic firefights, but you learn to manage them. Picking it up is simple, mastering it is the real challenge. You will see total chaos everywhere.
Inside the madness, the controls are neat but tricky, which is kinda weird anyway, their movement and shooting physics sometimes don't cooperate. You have to manage dodging enemy fire in tight spots with quick reflexes. Switching weapons is a simple button press. The interface could use some polishing, but it's manageable once you get used to it. You need to click to move and shoot.
Quick tip, i discovered that managing your movement is more important then just shooting wildly. You must practice the wonky controls during calm moments so you are ready for the chaos. The physics can be tricky, but learning them helps you survive the overwhelming enemies. It is better to switch weapons often. i found this thingy makes the game less frustrating.
Control is the main stuff you need to learn here. The buttons let you move and shoot, but the physics make it feel wonky. You have to manage your weapons and dodge fire. The adrenaline rush comes from the fast pace. It is easy to start but hard to master. The chaos is total and the enemies are overwhelming. This is the core of the game stuff.
