The Needler is one of Halo’s best inventions, with its bright pink spikes and explosive ammunition. It doesn’t matter if you’re using the Needler to blast through waves of aliens or take down other human opponents in multiplayer; you’re going to have a lot of fun. This alien SMG delivers its spiked ammo with a homing ability, locking onto evasive enemies and chasing them down. If you’re able to pack enough of the ammo onto one enemy it will explode, usually resulting in a point in your favor (or progression through the level).
There are only a few downsides to the Needler, namely its inconsistent nature and awkward range. There’s an inherent risk and reward factor to using the Needler, as you are often left vulnerable while waiting for the accumulative explosion. That said, laying into an enemy team with countless Needler shots is an ultra-quick way to get them tilted and annoyed. In campaign, the Needler is an easy pick simply for the visual flair that punctuates your successive kills.
