Trees are so last year. The vegetation of the future is the cactus, the succulent plant best suited to arid climates, barren wastelands and Mad Max-style post-apocalyptic deserts. For proof, you need only look at the games revealed during the last six months: first Bethesda's Fallout 3, then id Software's Rage, and now Gearbox's Borderlands. Road warriors of the world, unite!
But Borderlands can tick more buzzword boxes than just those related to flora. 'Co-operative' is on there, as Gearbox are designing the game from the ground up for both solitary play with AI teammates and four-player co-op with friends. 'Open-world' is another: Borderlands' desert can be explored and travelled in any direction you see fit.
