Do you know who you were? Nobody. Except on the day after the end of the world, you were still alive. And in Ppllaayy's shooter defense game Nuclear Plant, you have the chance to be somebody, entrusted as you are with growing one last seed into a tree capable of restarting life on the planet.
You need to grow the tree yourself, fighting off waves of enemies to buy yourself time to run the incubator. Move with [WASD] or the [arrow] keys and aim and fire your weapon with the mouse. In between waves, research upgrades by holding [S] in front of the lab, and activate the incubator the same way. Guns can be purchased in the shop, though it's not clear who you're buying from.
Nuclear Plant doesn't do much that Dude and Zombies didn't, but the post apocalyptic world is brought together through desolate scenery and an army of mutants and monsters out for your blood. It's short but the pacing is perfect, the weapons feel like worthwhile upgrades, and the game reaches a satisfying, though dark, conclusion. It may not teach you any real survival skills, but as a coffee break sized apocalypse, Nuclear Plant will grow on you.
