Publisher Warner hopes to achieve big sales on DS this year with new IP Lego Battles and Scribblenauts.

For Lego Battles, the publisher is giving away free entry tickets for Legoland Windsor. The vouchers indicate that kids can get into Legoland for free for every full-paying adult, and Warner hopes this will attract parents on a budget.

“Lego Battles and this offer to allow kids to go free to Legoland Windsor provides our customers amazing value for money holiday entertainment at a time when the family budget needs to stretch a little further,” commented sales and marketing director for Warner UK Spencer Crossley.

“Lego Battles is a quality game guaranteed to keep the kids occupied all summer and the opportunity to save money going to Legoland Windsor extends the Lego experience for all the family.”

The promotion follows the news that Warner’s other big DS title, Scribblenauts, took home a plethora of E3 awards  earlier this month.

IGN gave the game five awards, including Best DS Game, Best Puzzle Game, Biggest Surprise, Best Artistic Design and Special Achievement for Innovation, while Gamespy  and GameSpot voted it the Best Overall Game of Show. The DS title also secured two MTV Multiplayer’s awards, including Best Original Game and Best Handheld game, while 1UP called it the Most Innovative Game of the Show.

“We are truly honored by all of the E3 awards,” said 5th Cell lead designer Matt Cox.

“Scribblenauts will bring an exciting and completely original gameplay experience for both hardcore gamers and those who have never played games. We could not be more excited to unleash Scribblenauts to the world.”

Scribblenauts is due on Nintendo DS later in the year, Lego Battles will hit shelves on June 26th.
