You can pick up the game and begin playing very quickly. Then, when/if you are interested, you can poke in the dimmer recesses of the game and get into the strategy (or just ignore it altogether!).
At its lowest level, Scorched 3D is just an artillery game with two+ tanks taking turns to destroy opponents in an arena. Choose the angle, direction and power of each shot, launch your weapon, and try to blow up other tanks. That’s basically it.
But Scorched 3D can be a lot more complex than that, if you want it to be. You can earn money from successful battles and use it to invest in additional weapons and accessories. You can play with up to twenty four other players at a time, mixing computer players with humans. There’s a variety of changing environmental conditions and terrains to be dealt with. After the end of each round (which ends when everybody dies or there’s only one person left), you get to buy stuff using the prize money you won from previous matches.
