So, i got 3 achieves the day before the bundle was even released thanks to fact that all but 2 can be completed without searching on a bullseye DLC map, so here’s some tips for 3 of the achieves:
One Man Army-
This one is VERY straightforward, grab a rocket launcher and get 4 kills in a row with it, i did it on complex CTF but if you can think of an easier place go for it, so the best way to get this is defend an objective from a sly location or stick to indoors locations, and pack Ammo armor mod so you have room for error.
Pitchin A Tent-
This sounds super easy, but its not, for a few reasons, first, you have to stow yourself away somewhere you wont be found since you have to stay PERFECTLY still, so if you get killed or even shot, it’ll reset the timer for this to 0.
secondly, its not perfect at counting your AFK time so it may take more than 60 seconds before it unlocks, just stay still till its unlocked and only move then, don’t move after 60 seconds or it might not unlock.
I use the ridge bits that snipers sometimes use to the sides of each base in Ragnarok for this, crouch so i couldn’t be sniped, and just waited till i got the achieve.
Repeat Survivor-
This was a fun one, to do this effectively, i suggest you get a friend or two to help you. the trick with this achieve is, you can actually get it if your teammates destroy the vehicles with you in.
So me and a couple of friends got CTF Ragnarok, i would get onto the mongoose, they would then melee it until it blew up, rinse-repeat 3 times, and achieve unlocked, but stay alive, you have to get all of the ejections within one life.
So thats the 3 i got today before the bundle came out, hope these tips help you, especially that Repeat Survivor one since it means you can avoid using that armor mod online in the future if you don’t like it or prefer another mod.
