Monday's Installment in Team Fortress 2 - A Heavy Update may have taken all day, but it is extra-heavy, offering details on Arena Mode, a new game type that will come along with the upcoming Heavy class update for the teamplay shooter. The mode will play on five maps to start, altered versions of Well, Granary, and Badlands, and two new maps, Lumberyard and Ravine, and here's word on Arena Mode:

NO TIME FOR CRYING!
TF2 Arena keeps the class diversity of Team Fortress 2 while focusing goals around combat between two teams. Where other game modes lean towards a broad overall strategy for the team over a number of lives, Arena concentrates on the specific tactical choices the teams make in a single fight.

Arena features smaller maps that play out in shorter periods of time. The round ends once one team has no players left in the arena, or when the central capture point has unlocked and been captured. Rounds tend to be very fast and highly competitive, with an emphasis on your team’s class makeup and your plan to counter the opposing team’s class choices. Arena mode is great for smaller matches of three vs. three players, while still comfortably supporting huge knockdown twelve-on-twelve brawls.

ARENA CLASS STRATEGIES
Health pick-ups are limited in TF2 Arena (some levels don’t have any Health packs at all) so being careful is a good strategy for any class. As well, with so little health available, having a Medic or a Health dispenser-building Engineer on your team can be a crucial element to success. With their reconnaissance abilities, the Scout and Spy play a far more vital role in Arena than in other game modes. Knowing the location of the enemy team can often mean the difference between a win and a loss. The Soldier and Demoman will find many areas in Arena specifically designed for them to get a vertical advantage. Traditional Heavy/Medic pairings will still be highly useful as the anchor to a good Arena team. However, commit too far in this direction and the enemy can quickly overwhelm you with Snipers and Spies. In Arena, water is as scarce as Health. This makes the Pyro a much deadlier class, as any enemy player he sets on fire with his flamethrower or flare gun will be unable to put out the flames. Igniting enemies quickly, then retreating to safety, can be an effective strategy for the Pyro.
