Players will still earn unlockable weapons randomly, but the weapons and items can now be gained in the traditional fashion by steadily earning each class' achievements. The Sniper and Spy unlocks come at 5, 11 and 17 achievements, while previous class unlocks come at the 11, 17 and 22 mark. The patch also fixes a number of bugs introduced in the recent Sniper vs. Spy update.

The full patch notes follow:

• Added Sniper/Spy milestone achievements as an additional way players can get the new unlockables
• Arena Mode
  • Added tf_arena_use_queue server convar. Turn this on to get the old queue behavior. Default is off
  • Added tf_arena_round_time to set a timelimit on the round

• >Fixed player killed event causing server crash

• Fixed attackers seeing the mini-crit particle effect for full crits if the victim has the Jarate effect enabled
• Fixed the Ambassador not doing damage to buildings
• Fixed Spies disguised as their own team not drawing blood effects
• Fixed players killed by flaming arrows not showing the appropriate death icon
