Team Fortress 2 received a fairly significant update today, which adds a number of gameplay tweaks to Valve's multiplayer shooter - mostly for the Engineer and Spy classes. Following the update Engineers will be able to upgrade teleporters and dispensers to a third level, providing faster recharge and dispensing rates, while Spies will gain the ability to recharge their cloaking devices by picking up ammo.

The update also includes some new user interface features, such as a revamped HUD to show things like deaths by critical hits, players that are overhealed, and giving more information to medics when people are calling for them. Valve also revealed that next in line for the class updates will be the Scout, particularly focusing on making him more useful for the Dustbowl and Goldrush maps. They're soliciting ideas from fans, so head to the forums if you have any.

Finally, the company also mentioned that they are working on a "massive" update for TF2 on the 360 which will include all the new content that the PC version has seen in the past year, and revealed some engine improvements from Left 4 Dead will be coming to TF2.
