Easy Gem Farming...
	Various Achievements...

There is an easy way to get all the upgrade gems you need right at the beginning of the game. No need to compete for them with co-op players later on.

Here is what you need to do:

Start the first mission from the beginning and run to the first chest.

This takes about 30 seconds.

Open the first chest. If you do not find a gem restart the mission.

If you find a gem you will need to go to the next checkpoint to be able to save it. If you quit here it won't be saved the thing that makes this is a good farming spot is that the next check point is close by and there is another chest on the way so you have a chance to get a second gem.

A few steps past the second chest is the check point now.

Now you can restart the mission and make the run until you get the all the gems you need.

Less than an hour you can have every gem with duplicates.
