Hello, and welcome back to the Big Tank! This is an evo game where each poster progresses the evolution of a species by adding a single trait to them in paint or the art program of their choice. Try to make the species better adapted to their environment, but keep an eye out: Halfway through the thread, I will post a Big Tank Forecast with a warning of what the following thread's environment will be like. At the end of the thread, I will pick up to six species to survive and be the starting species for the next thread.

Era four is COLD, DARK, and SALTY. Much of the ocean is covered in ice year-round, leaving the water that is left extra salty and untouched by the sun. It is inhospitable on top of the ice or on dry land, but at least there's sunlight...

As you can see by the opening image, our surviving species are the Pleamp, Tlump, Scut, Schutto, Bloon, and Bleengi. Their individual posts will follow.

Remember to link your evo to its direct ancestor, as this makes it easier to trace evolutionary trees.
