The smooth movement combined with arcade-y gunplay is what makes shooting zombies and robots super fun. Go for a high streak with a shotgun, wallrun and grapple to traverse the map quickly, dash and double jump to dodge enemy projectiles, and/or use a windblast to clear out a group of zombies. Once on the battlefield, enemies will be relentless and never stop. Your objective is to secure zones and then escape through a portal. However, with each zone secured, enemies grow stronger and faster. So keep moving and keep shooting. To counter enemies becoming too powerful, aim for kills, high streaks, and/or secure zones to fill up the upgrade bar. Once filled, you are granted an upgrade point. Use upgrade points at any time during a run to enhance your base abilities and also receive a MAX HEALTH, DAMAGE, and/or AMMO CAPACITY bonus multiplier.
