Maximize your time
When you jump into a mission in Helldivers, there’s a lot more to do than just the primary objective. There are sub objectives to complete, enemy nests to wipe out, discoverable points of interest, and more. When you drop, you want to get as much done as possible in the time that is allotted in order to maximize your rewards. What helps out greatly with this is a strategic drop point.
Don’t simply pick the main objective as the location to drop in to. Look at the map, and drop into whichever objective or sub-objective is furthest away from the evac point, which is displayed as an arrow pointing upward. From there, make a mental note of the path you want to take in the mission to knock out as many tasks as possible, and always leave the closest objective to the evac point for last.
It’s highly likely that when you get to that final event, you’ll be glad you’re a hop, skip, and a jump away from evac, with the clock running down and your reinforcements dwindling.
