Developer Tripwire Interactive has released a new developer diary video, which details Killing Floor 2‘s weapons and perks.

Tripwire president John Gibson explained that one feature unique to Killing Floor 2’s weapons are the reload animations. Whereas the average reload animation is 30 frames-per-second, Killing Floor 2’s reload animations are highly detailed 200 frames-per-second, which makes them look smooth when you activate the game’s special “Zed Time,” slow motion ability.

In Killing Floor 2, each perk you choose at the start of a game is paired with a starting primary weapon and a specialized grenade. For example, the commando will start with an AR-15 assault rifle, while the support classes will start with a shotgun.

Starting a month after the events of the first game, Killing Floor 2 takes place on continental Europe, where a virus that turns people into monsters has spread.

Killing Floor 2 is slated for release on PC and PlayStation 4 in 2015. For more on the game, check out GameSpot’s previous coverage.
