TERA is primarily an action-driven fantasy MMORPG, yes, but that doesn't mean the game doesn't have a fair number of items that can only be described as 'out-of-place'.
TERA PUBG collaboration aims to deliver a few such tongue-in-cheek cosmetic additions to the mix, too, with TERA players soon getting the chance to bolster their selection of skins with some iconic PUBG additions, though a battle royale mode is nowhere to be seen. Yet.
The main attraction of TERA PlayerUnknown's Battlegrounds crossover will definitely be the temporary introduction of PUBG-themed BAMs (big-ass monsters) to the mix. Players will have to seek them out and take them down for special rewards, all this with decorative jeeps and planes littering the landscape around Highwatch.
TERA's PUBG crossover event is going to last a full month, starting on 5th of March, so if you'd like to get some special cosmetics and the like, as well as spice things up a little in TERA's overworld, that's when you want to join back in.
Keep in mind that TERA will feature special daily login bonuses - which haven't yet been revealed - for the duration of the event, so even if you're not particularly interested in non-fantasy PUBG cosmetics, there's something to keep you entertained.
