You also get free two track packs along with the base game.
Codemasters has a number of current racing games that are worth getting into, the latest being DiRT Rally 2.0. However, for those who haven’t sampled the developer’s racing offerings – or just like great games that are free – GRID 2 is currently free on the Humble Store. It also comes with two free track packs – Bathurst and Spa-Francorchamps.
Simply head over to the Humble Store, click on “Get The Game”, and you should have the Steam keys for the game and track packs delivered accordingly. Keep in mind that the offer is only valid until March 17th, 10 AM PT. Also the offer is valid for as long as supplies last, so hurry up.
Furthermore, you need to redeem the keys before March 21st, 10 AM PT. If you don’t, they’ll expire and be pretty much useless. As for whether GRID 2 is worth playing, you can check out GamingBolt’s official review here. Track variety is kind of “meh”, but otherwise the single-player experience is well worth it.
