WARNING! POTENTIAL SPOILERS AHEAD! I've got into the newest add-on for ME2 and am having a blast so far. Anyhoo, I've noticed on the driving sections that there are sort of circular 'waypoints', which can have what looks like fuel canisters in the middle. Am I supposed to be able to pick them up? I've tried every button and can't seem to do anything. I wish the Hammerhead had been in ME1. Lovely little vehicle!
Are you talking about the info stashes (or whatever they're called)? The way to pick things up is to use the "prospecting" button. You hold it and have to maneuver the Hammerhead so it stays in the circle until the prospecting process is complete. If I recall correctly the button is either left shift or space bar (the lights on the back of the Hammerhead should turn on starting with red and turning green). You can also collect extra resources this way as well.
Ah, that sounds like it! I wish they'd included some sort of tutorial. Playing with a custom key mapping doesn't help either .
You can also boost and jump while in the Hammerhead. It's quite fun to just drive around in. Overlord is a pretty awesome piece of DLC too. Also, have you tried the Aegis Pack that just came out? Apparently it has a new sniper rifle in it.
Yeah, that one introduced the Hammerhead so it has a tutorial. Kind of an oversight to not have any instruction in Project Overload, but I guess they figured everyone would have it already since it's included with Cerberus Network.
