Until We Die is a unique take on base defense strategy set deep underground in a subway station. After meteorite impacts bring all sorts of dangerous creatures into your world, your mission is to hold the fort for roughly 30 game days. At the start, you'll be fighting off small groups of attackers, but as time goes on, you'll face increasingly large and ferocious mutant hordes. The game challenges you to protect your base at all costs—if Ivan, our main character, falls or the essential power generator is taken out, it's game over.
