2. Sniper Elite 4 Tips

Before you begin the grind, here and a few tips that should make the process a little easier:

While most achievements will be easy to net, 3 difficulty based achievements will present the only real challenge you’ll encounter. Completing the game on authentic can be tough, but authentic plus without the use of manual saves is brutal. It can be a rage-inducing experience, but with patience and a little luck, it can be done.

Outside of authentic plus, the majority of achievements will unlock through natural game progression. The DLC includes a few tricky challenges, but nothing remotely close to the difficulty based achievements.

Upgrading a rifle, secondary weapon, and pistol is required for two achievements. It’s recommended that you work on these upgrades whenever possible, but don't stress if you're not making much progress. Weapon related achievements can be finished while playing Survival. You can access the requirements for any weapon via the loadout screen.

Be sure to interact with every NPC before launching the mission. These characters will provide you with information regarding secondary objectives that you’ll need for 4 separate achievements. Follow the objective icons on the map, and be sure to check all secondary objectives to ensure they're being completed before ending a mission.

The Silent Warfare Pack includes the Delisle Carbine. Unlike other rifles, the Delisle doesn’t require suppressed ammo. This will make the process of grinding achievements much faster, as you needn’t worry about searching for suppressed ammunition. It's Paid DLC, but it's entirely optional; any rifle will do.

Note: This walkthrough couldn't have been done without the help of other gamers gracious enough to provide supplemental video. Be sure to give them a like as a token of appreciation!
