Loadout Guide
After 500+ missions completed with the Engineer, I can conclude that this is my favorite build. It takes the one thing the Engineer lacks in, which is mobility, and cranks it up to 100. Mastering the RJ250's movement is one of the most rewarding and fun game mechanics DRG has to offer. The LOK-1 Smart Rifle paired with the Seeker Rounds overclock makes up for the lack of firepower the RJ250 Compound Deepcore 40MM PGL lacks, making this one of the most well-rounded builds the Engineer has. Good luck zooming through the caves, and gathering Nitra faster than your useless Greenbeard Scout!
Primary: LOK-1 Smart Rifle + Seeker Rounds
The Smart Rifle is the bread and butter of this build. I chose to go with 2-3-1-2-1 on this, although you can change a lot of the upgrades to your liking. This overclock essentially gives you aimbot, allowing you to shoot bugs behind walls, and always hit the bugs' weakspot. Despite making you shoot slower, it isn't noticeable enough to notice a big difference, and the same goes for the longer reload time. This makes this weapon completely busted, being able to kill every bug with ease, and requiring little to no aim.
Secondary: Deepcore 40MM PGL + RJ250 Compound
The PGL is the heart and soul of the build. The main appeal is being able to rocket jump like Soldier from TF2 and keeping up with the best of Scouts, while still having the main swarm-defending qualities the normal PGL has. I chose to go with 2-1-1-2-2 for it. The ammo upgrades are necessary, because you'll find yourself running out without the extra 4 ammo when in a tight spot late into a round and no resupply. The incendiary compound is also necessary, because the RJ250 OC decreases damage, no longer allowing for a one shot to grunts, so the fire buildup will finish them off. The last 2 upgrade spots aren't mandatory, but I like to have the larger area of effect to deal with any swarmers.
Utility
I run 2-1-3 on the platform gun. The extra ammo is a must because the other 2 upgrades aren't worth your time. You could be useful to your time by choosing Repellant Additive in the 3rd slot, but who cares about that anyways, we're going with the Disabled Inertia Inhibitor so you can save yourself from fall damage easier. For the sentry, engineering suit, and pickaxe, I went with the default best upgrades. For the throwable, I went with the SSGs because the other grenades are simply not good options for roaming with engineer. The Lure might work well with the grenade launcher, but you want to save your ammo for getting around. The Plasma Burster is a decent option, but not better than the SSGs, and the proximity mines are really only useful for setting up in one area, which is what this build is not about.
In Conclusion
Beat your dirty Scout loving peers to nearest Morkite vein, and then flex on them in chat when you get more materials mined than them. I hope you enjoy playing with my first (and only) build on karl.gg. Rock and Stone Miners!
