… But hold on to a (Retro) Lancer
Switching out guns is great, but try to stick to either the original Lancer or the Retro Lancer in one of your two available weapon slots. Your Gnasher shotgun may be powerful, but it can more easily be swapped out for a pretty common Overkill. The Lancer and Retro Lancer have abilities of their own, which makes them incredibly useful in fights and pretty rare to come by in combat.
The standard Lancer has a chainsaw that can be revved up and slice an enemy in half. This conserves ammo and quickly takes out an enemy, whereas the Retro Lancer’s bayonnet lets you charge across the battlefield and impale the opposition.
The best thing? These abilities require no ammo. Even if you’re all out of bullets, you can rely on the undermounted attachment to get some killing done for you. Besides, there’s still one weapon slot you can switch out, so make sure to apply tip #3 for at least one primary weapon. Make sure to diversify your weapons, soldier!
Another major bonus is that these Lancer variants remain effective at any range. The Hammerburst is also a valid alternative for mid-ranged combat, but do remember that this three-round burst rifle can make you run through your ammo at an unexpected pace, as well as providing no passive abilities like the chainsaw or bayonnet.
