League of Legends, the team-vs-team title that was inspired by the Warcraft III Defense of the Ancients mod, was released last week and the good folks at Riot Games provided us with a package of goodies to give away to one lucky Co-Optimus reader. Want to know what you can win and how to enter? Click the link for all the details.
It's been a few weeks now since Halo 3: ODST's release. Perhaps you see your friends still enjoying the game's Firefight mode and whimper in jealous. You get the constant invites of a group needing a fourth soldier for a legendary run through the campaign and curse your empty wallet. Sadly you've yet to pick the game up, we know, we all have our reasons for avoiding it - but now there's no excuse.
We're giving away one copy of Halo 3:ODST including the exclusive Sgt Johnson Firefight character to one lucky winner!

When purchasing headphones, I will rarely if ever even glance at ear buds for any reason. To me, ear buds are the cheap inserts that come with products, mildly uncomfortable with sub-par sound. That is, until I tried out the Tritton AX Ear buds that I received at the Blue Skittle Party at PAX. Starcraft was my first test with its phenomenal in-game sounds coming through loud and clear, then on a Nintendo DS to see if they worked just as well on the road.

The third map pack for Call of Duty: World at War hits Xbox Live and the PlayStation Network today, complete with a brand new co-op zombie map and monkey bombs. To celebrate we're giving away two codes for the Xbox 360 version of the game.
I'm feeling generous this evening, so lets do a giveaway. Up for grabs are two copies of Call of Duty: World at War for the PC. To enter to win all you need to do is leave a comment on this post! It's a simple as that. Of course it wouldn't hurt if you told your friends, relatives, pets, and badgers all about Co-Optimus.com and our awesome contest too.
We'll pick two winners, one copy each, on Sunday, May 10th. Good luck!
Last night we had a very successful Xbox Live Co-Op night featuring Resident Evil 5 on the Xbox 360. But we don't want to leave our PlayStation fans out in the cold, so we're giving away one copy of the PS3 version of the game to a lucky reader.
And while we don't promote (or even condone) versus gameplay on this site, we do have a code for the Xbox 360 version of the Versus Mode DLC.
To enter to win either item simply reply to this thread and tell us what you want to get your grubby zombie paws on. Winners will be drawn this Sunday, April 12th, at 9PM Eastern.

Activision has released a brand new vignette for the recent map pack for Call of Duty: World at War. The video focuses on the new four player co-op zombie map, Verrückt, that comes in the map pack; and hot damn if this isn't one of the most badass trailers I've seen in ages.
In fact, I guarantee after watching it you'll want to instantly purchase the aforementioned map pack on Xbox Live or the PlayStation Network. If you fall into the former category, hold on to your wallets, because we are giving away two free codes for the map pack!
To enter simply leave a comment and tell us your favorite zombie appendage to shoot off. We'll draw the winners tomorrow at noon. For now, watch the trailer...we dare you!

I remember when we were hyping up Castle Crashers. It was one of the few co-op games we knew were going to be a stand out title. Four player online, easy pick up gameplay, and graphics that just ooze style. Then the game was released, and our hopes and dreams were dashed. What we got was a great couch co-op title that severely lacked any workable online.

Welcome to the final day of our humble little, uh, LittleBigPlanet promotion! Today we have something special for our Co-Optimus readers - some super sexy wallpaper for your desktop or laptop PC featuring our very own Billy and LBP's own SackBoy!
Today is also the final day of trivia. We have one more question for you to answer. But for what? Answer all questions correctly and you'll be entered to win a free copy of LittleBigPlanet!

They always say one person's loss is someone else's gain - and in this case that will be one lucky Co-Optimus member! I can't even begin to describe everything in this bag of swag, but there's at least a half dozen t-shirts, a couple dozen stickers, hats, action figures, cases, notebooks, games, dvds and more. A lot of this stuff is rare promo materials...other stuff is just plain cool.
So how do you win? Simply sign up for an account if you don't have one already and post a comment in this thread! I'll pick a winner on Thursday. Welcome to Co-Optimus!
