I think Extinction and Sun Scorched are the best-looking themed skins in the game and the red line m16 is from the era of grounded pubg skins that players had to actually earn with skill. I don’t regret upgrading the shotgun to max level, even if it’s a meme weapon outside of early game.
used schematics from season passes and free contraband coupon openings to upgrade it. I had to save up for 2 years to have enough schematics, but I did it for free.
