Survivalist
Survivalist is a lane shooter where you lead three survivors down a single road. Your squad shoots gates, crates, and enemies that move through the lane. A gate pays more the longer you hold fire on it, so a +1 gate can climb to +20 if you keep shooting it. You time your shots, pick the right gate, and move to stay alive.
Gates usually arrive in pairs with a lethal pillar between them. You have to pick a side and choose the ×3 or +18 gate, not the ÷5 gate. Green crates make the squad hit harder, and blue crates make the squad shoot faster. You also dodge solid objects and kill what comes down the lane. Every stage ends with a boss, and if your squad dies, the boss comes back weaker.
