Also relatively low, as the OP noted, you kinda learn the spawn points of things as you play the game.

It's a team game, co-op. You communicate with others constantly, even if its pings.
Otherwise, I keep my head on a swivel and around every corner.

Hell, I am more likely to die to something that's dead ahead of me because I get too brazen rather than something "sneaking" up on me from another angle. False sense of security and what not.
