Orbital laser, napalm strike, grenade launcher, supply back pack, vitality booster.
Depending on a mission I might switch out some stratagems but that's pretty standard loadout the last day or two for me. Level 17. Playing hard typically but about to bump up to the next difficulty
I wish I weren't such a basic bitch with the Breaker, but the way it can blow brood commander's legs clean off and dig through a warrior's armor is just too good. Plus, I'm generally on recoilless duty and can usually solo a Charger with a rocket into a front leg followed by a breaker clip into the exposed flesh.
Highly dependent on who I am teamed with and what mission we are doing. I would suggest to not sleep on the impact grenade and the Eagle Air Strike though.
Only just made level 7 today, and I'm trying to keep my accuracy above 70% with Marksman +Uzi +HE grenades, and swapping out Strats per mission params (leaning heavy on Eagle Strafe and Gatling Turret, though I've only been bug hunting [PSA: fuuuuck Bile Titans 🤬🤦🏼♂️])
I'm around level 35. My playgroup all run shotguns so I typically use the marksman rifle to provide covering fire ( the counter sniper is awful, don't bother). Light armor every mission; armor rating is bugged but besides that you can out run anything except chargers; just remember to kill hunters and stalkers.
Expendable Anti Tank every mission. Every minute you can kill a charger or another elite. They can also take out bug nests and bot factories. Just throw them out and let your team use them if they want to. Every minute you have a strategem to drop on someone's head or into a big hole. I can't stress enough how great it is to have these.
Autocannon/Railgun. Auto Cannon can take out nests, factories and eggs. If anyone else decides to help reload you can go full automatic and kill everything. Remember to reload yourself between 1 and 5 shots to get the quick reload.
Railgun is mostly to 1-2 shot hulks in the eye. Otherwise it can kill anything if you are alone.
Then free slots for experimentation. I like the gas for softening groups, all eagle gems are good, and the 380mm barrage for killing my friends. The personal shield is great but I am not a coward.
The mortors make exterminations a cake walk. I otherwise avoid the turrets since they aggro everything around you and I usually walk around every pack. I may start using them as a distraction though.
been digging the arc thrower, jetpack, EAT combo against the bug bastards lately. last slot is circumstantial or experimental.
having the jump pack pairs super well with the arc'r since you can both get on high ground for better clearance and/or get a few extra zaps in before jetting to safety.
arc thrower was scary to use at first due to the team kill potential, but I rarely hit people now and it is so great at keep hordes at bay.
I'm not as comfortable against bots so I follow more of the 'meta' load out with rail gun and eagle strike.
Guard dog laser drone makes dealing with the little but annoying bugs super easy to deal with.
I like the normal eagle airstrike but I'll use various ones for the mission. Some reason I like airstrikes better than orbitals despite the cooldown being harder to manage if you have multiple.
Mortars (only with the boys on the mic because people don't seem to understand they will blow you up?) , Breaker, that extended mag pistol is a life saver up close, that Emp stratagem, Rover Lazer and of course that shield.
