Talk about intense! D'you think the players in this trailer for Warside ever take their finger off the firing button? When I first started watching the trailer above, I initially though this was a 2D platformer/shooter in the vein of either Shadow Complex, Intrusion 2, or even the recent Strider reboot. Turns out Warside is an online, team-based game with an RPG system too.
Currently on Greenlight and developed by Russian studio Kraken Games, Warside has got co-op action, which is something that's always going to get my interest. The idea of a 2D online shooter is pretty unique too; I wonder how well you're going to get a sense of scale or what your entire team is up to. Something like Awesomenauts works due to its MOBA-style gameplay and small player count but Warside looks pretty different.
Also it has jetpacks which is a big thumbs up from me.
