Once you have about $4000, you can purchase something called "Spirit Map A", or something like that, from the Milk Barn, from the greaser guy. It'll cost you $2000, and you'll need to stock up on some first aid with the rest of your money. Buying the map will start the sidequest called "Cope's Tunnel". The mission is basically 4 arena-style rooms with around 5-6 zombies in each room, most of which are pretty easy. However, the last room has a bunch of zombies with shotguns, which is actually pretty hard, hence the suggestion to stock up on first aid. Feel free to use all the SMG ammo you have gathered so far, you won't be needing it soon. Otherwise, you can just grind it out by using stimulants to sneak around for extended periods of time, then just use your melee weapons to kill the zombies quickly.

At the end of this you will get an Infinite Ammo SMG, which pretty much allows you to blow through most of the combat, making the game much more enjoyable in my opinion.

Cool tip. Just another similarity to RE5.

Really, you get enough 10mm ammo that it isn't too big of a difference, but it also has double the capacity, so that's always cool.
Also, for that last challenge room, hold your breath to sneak by the shotgun zombies and get to cover so you can duck behind it when they take a shot at you.  Or shoot them in the head when they're charging it, that works too.

But then that would make for a fun ER. The point is that they're stumbling about, trying to figure out what the hell they're doing. To look up "cheats" and hints such as these will ruin the spirit of ER.

Yeah, but the game leads you into a lot of these sidequests by telling you on the map where you can go to get them.  This one starts at the convenience store, so they'll probably see it when it first shows up regardless.

Seriously the infinite smg or shotgun are necessary for playing through the game.

Does anyone know if there is a way to get the cope tunnel marker off the map?  I completed the quest and scored the gun but the orange marker is still there.

Sadly no, and I don't know why.  It's a different color than the normal mission flag and easy to avoid if you use Cope's Tunnel.  Still, I agree it should not appear on the minimap once you've beaten it.

I don't mind that it stays there, it's a great place to refill on shotgun ammo if you use it a ton.

I wonder how the Endurance Run will go once they run into the wall-crawling zombies. Just ran into those yesterday, and they took FOREVER to kill with the infinite SMG. Then I discovered you could kill them rather quickly with my Infinite wrench, which is also a useful item that can be gotten through sidemissions.

When is the earliest time you can pick up these sidequests?  I'm stuck with low ammo facing crawlers under the gallery in chapter 2 pt. 2.  I'm trying to decide if I should go back earlier to do the infinite smg sidequest, but obviously I don't want to do that if it's not gonna be unlocked yet.
 

I believe the SMG quest unlocks at Chapter 6. But the SMG doesn't help much against the wall-crawlers. Melee weapons and the flamethrower take down the crawlies the fastest (The flamethrower can be gotten starting at Chapter 6 by getting all the bones and bringing them to Brian...but you should bring them all at once to Kaysen first to get the infinite magnum).

Flamethrower did the trick, thanks!

The Infinite Magnum makes most enemies in this game a joke.
 
You've got a guitar to deal with the rest.
