4. Bugs & Glitches
Oh, lord. Bugs are common to any game, but shooters can really suffer, especially due to their competitive nature. If there is an issue, it can take weeks or months to be fixed, leaving the game quite broken and unplayable in the meantime. Things like MW2's Javelin glitch come to mind: for those who don't remember ,the Javelin glitch occurred when a player used the Javelin weapon after cooking and restowing a Semtex grenade, causing them to explode upon death killing every enemy in a 30 foot radius. It's beyond me how these things can get through the testing phase of development. Or take the M26 MASS glitch from Battlefield 3 - after one of the patches, using the under-barrel shotgun with certain attachments made the MASS behave like an assault rifle, allowing you to one-hit enemies across long distances. Same went with the smoke launcher and AUG A3 assault rifle. It's frustrating when this happens, to say the least. Sometimes a dev issues a fix within days, other times, like with Battlefield, players need to wait months. While FPS games don't come with any subscription fee, meaning it costs us nothing to wait, we just want to play the game, and a game you can't play is a failure on the most fundamental of terms.
