Only one level stands between us and the boss of the third episode and it's a long one. We have ammo and health enough to get through that but it's not that level that's going to be challenging but the last one. Unlike the other boss levels we've encountered so far the one in this episode is quite long and full of enemies, whittling away at our ammo and health before we even get to the final boss. That said some of the enemies in that final level are fully capable of killing us before we even get to the boss. They can't stop us forever though..
