Go right and kill. That's the gameplay of Achilles, the flash game in which you play the hero of the Trojan War. Fresh from sulking in your tent, you're determined to kill every soldier that comes your way... and boy, are there a lot of them.
Achilles doesn't need to be explained at this point in gaming history. Stab and kick, pick up spears when you see them, use your shield to block, and maybe you'll be able to slaughter every level boss between you and victory. If the Olympians show favor on you, you'll survive until the end, and the poets will remember your name. If not... well, you've got three lives.
This isn't to say it's a cakewalk. It can be hard to hit soldiers when you're right on top of them, and if you get two archers standing side by side, they can pin you down with a rhythm that's impossible to beat. I actually got shot in the ankle trying to jump over a few (which is pretty funny, really) and they only get more skilled as the game goes on. But there's no glory without risk, and you've got a life bar to waste on these worthless Trojan dogs. Strap on your helmet and prepare! For today, you are Achilles the hero! Take that, Trojan face!
