Rockstar Games announces that High Life Week is now underway in Grand Theft Auto Online, the multiplayer component of Grand Theft Auto V. This includes the addition of two new "Inch By Inch" maps, discounts on some virtual luxury items, and rewards boosts between now and April 28th or Sunday. Or both, as the explanation references two end dates:

The relentless intensity of Inch By Inch climbs another two notches today with brand new maps available to play right now in GTA Online. You’ll be fighting tooth and nail amongst the muck and hay bales at the Grapeseed Cow Farm in Inch By Inch III or setting up security checkpoints for low flying bag carriers entering your end zone’s airspace at LSIA in Inch By Inch IV. Both of the new maps feature in the Double GTA$ & RP Playlist available to launch directly from GTAV boot screens all weekend until midnight on Sunday April 24th.

The Double GTA$ & RP Inch By Inch Playlist is just one of many bonuses & discounts live in GTA Online from today through to Thursday April 28th as part of High Life Week in GTA Online. All week long, take advantage of Double RP Bonuses and substantial discounts for Properties, Yachts, clothing, Weapons and more.
