Take-Two has released financial results for the its fiscal second quarter ending April 30, revealing profits of $16.9 million (up from a loss of $10.4 million during the same period last year) on sales of $268 million (up 54% compared to the same quarter last year).

Sales were driven by impressive and continued market performance by Bioshock 2, Major League Baseball 2K10 and GTA: Episodes From Liberty City on PlayStation 3.

Take-Two also revealed that, since the game’s launch in April of 2008, Grand Theft Auto IV has sold 17 million units worldwide through April 30th, while the Carnival Games franchise has sold 6 million units since its release in 2007.

In addition, Take-Two announced that Red Dead Redemption has sold 5 million units since its release in May. Although these sales didn’t contribute to the company’s second quarter financial results, they did lead to Take-Two raising its full-year fiscal year sales forecasts to between $880 and $980 million (from previous forecasts of between $725 and $925 million).

Games due to release in Take-Two’s fourth fiscal quarter (which ends October) include LA Noire, Mafia II and Sid Meier’s Civilisation V.

Max Payne 3, however, has been delayed out of Take-Two’s current fiscal year, and may appear during or after November 2010.
