Found this gem on steam on offer at the moment, nice little coop tactical game (also SP) if you are looking for an interesting team based game then this is a nice simple room to room game that gets harder with each floor, bit of a learning curve but easy enough to 'pick up and play'

Base game and DLC should come to £3.02 total which is well worth it imo
