Serious Sam 4

During the mission the four horseman when you're getting close to the objective "Place the second beacon" an a side mission for finding an artifact will pop up, complete this for the item. Then equip the item, find an area with a large number of small enemies without killing them, throw your time warp and use a strong weapon to kill as quickly as possible. After killing 5 your achievement will pop.

To get the Time Warp gadget, play thru Four Horseman of the Apocolypse until you’re on “Place the Second Beacon”. You’re looking for a side quest called “Amateur Archeology”, where you will collect the Time Warp Gadget.

I wanted to add the name of which side quest you’re looking for to the existing guides because I had to do this post game in Chapter Select, and there are a couple of other side quests before this one. I didn’t want to do any unnecessarily, yet I couldn’t find the name of this one anywhere. I realize the side quests will show the rewards under the mission list, but isn’t it just easier if people would list the name of the mission.
