If you're looking for some new entertainment titles for your Mac but you don't want to spend a lot of money, take heart: there are some fabulous deals to be had on Mac-compatible games this week. Whether you're looking for something new or a classic title that's still a lot of fun to play, chances are you can find something that's right up your alley.

Borderlands 2 for 66 percent off

Gearbox's phenomenally fun shooter with RPG elements Borderlands 2 is one of the high points of recent action gaming. The game takes you back to the alien world of Pandora as you become a Vault Hunter - a person looking for alien artifacts. You end up fighting nasty critters and other humans, collecting weapons and more.

A lot of people have already played Borderlands 2, but if you've been waiting for a good deal, don't hesitate, because for Friday and part of Saturday only, you can download Borderlands 2 for $10.19 - that's 66 percent off the regular price of $29.99. The game is SteamPlay compatible, which means you can download it on either a Mac or a Windows PC and play the same game through. DLC costs extra, but it'll let you play the game a lot more. And more DLC is expected soon.

XCOM: Enemy Unknown for 75 percent off

Another great deal on Steam this weekend only - XCOM: Enemy Unknown for 75 percent off, or $9.99. XCOM : Enemy Unknown puts you in control of a paramilitary organization tasked with fighting off an alien invasion. XCOM is the resurrection of a game series that was really popular a few years ago, completely reimagined for modern systems.

If you've never tried or seen XCOM: EU and you're not sure if you'll like, take heart that there's actually a Free Weekend running until Sunday. This way, you can download the game to try it out, and if you like it, just make sure to pay for it before the sale's over.

50 percent off Interplay games at GOG.com

Fallout 2

GOG.com - short for Good Old Games - specializes in classic computer games that have been resurrected to run on modern systems. Most of their games are reasonably priced to begin with, and none of them are encumbered with DRM. But every once in a while they have a barnburner of a sale, like this week: Interplay games are 50 percent off.

Interplay published some of the best-loved games of the 90s - Fallout and Fallout 2, Descent, Freespace, Battle Chess and many others. This weekend they're available at prices from $2.99 to $4.99. Now, these versions that GOG.com sells are typically DOS or Windows executables wrapped in an emulation layer, but I've played a bunch of them and they work well - just pay attention to system requirements before you download.

Batman Mac games for 50 percent off

GamersGate.com - another popular game download service - is featuring two of Feral Interactive's Mac offerings for 50 percent off. You can grab either Batman: Arkham Asylum or Batman: Arkham City Game of the Year Edition for $15 or $19.98 respectively.

Batman: Arkham Asylum plunges the Dark Knight into the home of Gotham's criminally insane. He must find a way to get out while figuring out what the Joker is up to. Batman: Arkham City GOTY takes you inside a part of Gotham you've never seen - a walled-off section of the city where criminals run amuck. Both games are intense, and definitely worth checking out if you're a fan of Batman.

Deals at MacGameStore.com

Those same Batman deals are available at MacGameStore.com, which is offering some other good deals too - you can pick up the newly released Mac version of the subterranean post-apocalyptic shooter Metro: Last Light for 10 percent off - $44.99; and if Sega Superstars Tennis strikes your fancy, you can pre-order the game for 40 percent off the release price - $8.99. That game's coming out mid-month, according to Feral.
