First strike. Did the first few missions like the brash young kinderguardian I was. "Strike? Easy" I thought. Loaded up the Devil's Lair. 55 minutes later, Sepiks dropped. 55 minutes of the most difficult fights I'd had on an FPS up to then. The fight with Lady Comstock or the last fight on the airship on Bioshock Infinite's 1999 mode was like the tutorial compared to the Devil Walker. And then came Sepiks. The sheer satisfaction of beating Sepiks for the first time actually compares to finishing my first Nightfall or beating Atheon for the first time.
