Helldivers 2

I switch it up a lot, but there are a few things I take regularly.

My secondary is the grenade pistol unless I take the crossbow or Eruptor since they are explosive. The grenade pistol is handy for closing bug holes, damaging tougher bots, clearing weak swarms, has a lot of shots and refills off of regular ammo boxes. If I take the Crossbow or Eruptor they fill the same role so I generally take the Verdict or Dagger for crowd control up close.

I almost always take Thermite for the nade and armor with the Engineering kit for the extra nades. They destroy factories, kill tough enemies like chargers and hulks, and some reinforced turrets. Sometimes I take Incendiary Impact or Gas grenades for crowd control when fighting the Illuminate or nids and using the Eruptor.

For primary I like the Eruptor on large open maps and the Liberator Penetrator or any shotgun for any map with low visibility. The Scythe and other laser weapons on a blast on cold worlds, but I tend to play on temperate or hot worlds and they overheat a bit fast for my tastes.

Stratagems vary widely depending on the map, but in general there is at least one orbital or eagle that covers a large area for clearing bases and one turret. The Guard Dog back back is great in almost any situation if I don't want to hop around with a Jet Pack or don't take a weapon that has a backpack already. The Recoiless rifle is my favorite antitank weapon if I need one. I tend to not choose a machine gun or flamethrower since I frequently find those in points of interest.

I cannot use the railgun consistently, pretty sure my aim gets thrown off when I let off the mouse button or I'm not sitting still long enough for it to settle or something like that. Too hard to figure out what I'm doing wrong without being able to see where the shot went.
