Go onto Xbox Live now and you can download sub-aqua shooter Undertow for absolutely nothing. Do it now, because this is a time-limited freebie that goes offline at 7:59am 30 January. The game will still play after that time, but it won't be available to download for free.
Is it any good? I don't know. I haven't played it yet. I tried downloading it at home this morning on the off chance it would be available early, but no dice. From what I can tell, it looks like a modern-day interpretation of Scuba Dive (you know, the old Spectrum game from Durell - no?). Maybe not. Let's see shall we?
If you're wondering why Microsoft are giving it away, it's to help promote the first ever Xbox Live Arcade Awards, which will be awarding gongs to the best Xbox Live Arcade games. Anyone can vote. If you fancy sticking your oar in, pop along to the Xbox Live Arcade awards site
Categories open to public voting are as follows:
Best Overall Arcade Game Best Classic Game Best Original Game Best Family Friendly Game Best Competitive Multiplayer Game Best Cooperative Multiplayer Game
Voting is open for the same duration as the Undertow free download.
