Exclusive: Snake-esque puzzler Hard Lines for iPhone and iPad to be updated with 2 new modes, in-app purchases, power-ups

Spilt Milk Studios's Silver Award-winning Snake-meets-Tron puzzler Hard Lines is set to be updated with two brand-new game modes.

The first of these modes, Daily Challenge, will be available through a free update, and will task you with completing a specific objective from one of Hard Lines's various game modes.

Successfully tackling this auto-generated mode will reward you with in-game currency (called Hard Cash) and "kudos" from your friends.

The second new mode is called Lionel's Hard Cash, and is partially inspired by Scrooge McDuck's Vault from the Duck Tales series.

Unlike the majority of iOS games that encourage you to buy bundles of in-game cash through repeated in-app purchases, this new mode offers "infinite in-game currency" for a single in-app spend.

Once you've downloaded the mode, you'll be able to compete for a place on the leaderboards, and earn enough in-game currency to splash out on any current and future in-app purchases.

Standalone packs of Hard Cash will also be available if you're a bit lazy, and the game's standard modes will be laced with free cash pick-ups, too.

All of the cash you amass can be spent on four new power-ups and a special Blaze of Glory bomb. This detonates upon your death, killing all on-screen enemies and scoring some extra juicy points.

Finally, that Android version of Hard Lines that we told you about back in August will be playable at this week's Eurogamer Expo event on a "shiny new Xperia Play".

You can pick up the Universal game Hard Lines from Apple's App Store now for 69p / 99c.
