Strategy
Usually there isn't a real problem killing this boss in a 4-player game. But to ease it up a bit, as always, take out any smaller infested first, then focus it down. Heavy melee works, but be ready to revive.

While the Phorid uses mostly melee attacks note that the Phorid has two ranged attacks:

One attack is the "scream" that will cause some damage, disorient you, and pull you towards it. Don't stand too close to the ledges if you plan on taking it out from a ranged position. Also turn and counter-run the other way if you must to avoid falling down.

The other attack is a number of "homing green bolts" that can hurt A LOT. This is especially troubling when soloing, as the damage bypasses your shields and may outright kill you. This might be countered by higher health.

Bug tactic The Phorid is perhaps agile, but can get stuck in stairs and tight places (edges) like other NPC's. Use this to get an advantage by luring it up the stairs, then take positions on the side shooting it. It might eventually get up the stairs but it may very well get stuck for good. (If it gets up and you're not up to killing it yet, jump down and repeat).

Freeze tactic. Another easy way to dispatch of The Phorid, is to equip a melee weapon with high attack-speed and freeze-damage. The constant freeze-damage will slow The phorid so effectively that it is possible to stay behind it, at all times. The only danger to this tactic is the "scream" that will stun you for a short while, but even this can be handled. Using this tactic it is not that hard to defeat this boss, in a solo game.
