Yes you have heard by now or at least I think you might have. This is the game to get if you have not played it before. Even if you haven't played the original, don't worry. This game starts with new characters and a new story line. If you played the original, then you will recognize some of the playable characters of the first has returned as NPCs in this one.
You cannot deny the concotion this game presents. You have RPG leveling elements and guns to collect. Side missions galore plus the story missions. The firefights are engaging. The enemies make you laugh with their off brand of humor. The references to pop culture are endless. Even the comic book like presentation gets you right into the mood.
You have four character classes to choose from (not including recently added DLC character class, Teknomancer) and to build with Skill Points that help you with your shields, life, Kill Skills and special powers.
This game is worth every bang of your buck and then some. If you're on the fence, don't be. I didn't know what I was stepping into but when I got started, boy, was I engaged (and still am) for hours, building my character and collecting guns.
If you played the first Borderlands and liked it...you get more of the same intense action and crazy guns in this game. If you are new to Borderlands...then jump in grab some guns and get shooting. This is a FPS with RPG looting and level tree elements and a great game. I really don't have much to add that you haven't heard before other than....what are you still reading this for? Start playing Borderlands!!
