Payload – Team Fortress 2
With its unique visual style and extremely intuitive gameplay, Valve’s cel-shaded online shooter is undoubtedly amongst the best multiplayer games of last year. To add to the two game modes (Control Point and Capture the Flag), Payload was introduced in the latest Team Fortress 2 patch, with a map called Gold Rush. This mode is like an escort mission, only you don’t have to escort a V.I.P. Here, you escort a bomb (which, as you might have guessed, is the Payload)!
The defending team ensures that the offense doesn’t get the bomb to their base. The way to do this is by killing the enemies near the cart carrying the bomb, which makes it halt dead in its tracks. I love the way each class comes in handy while doing this – you’ll have engineers set up turrets to hold up choke points, you’ll have a demo man lob grenades at the escorts, and you’ll see a heavy gunner upfront, with a medic healing his ass as they punch through the enemy defense.
Gold rush is just the first map of this gametype, and it owns. I can’t imagine how awesome upcoming maps for this game mod will play out. Let’s hope they turn out equally good, if not better; I have my fingers crossed (only when it’s not on my cel-shaded trigger).
