From onionman:
We’ve finally released two new missions to Ensign-1! Mission-4 the corridor crawling descent inspired level as well as Mission-5 with the ice crystals. In addition, previous missions have been improved with new scripted events, such as enemies decloaking mid-battle and areas where you’ll need to shoot fighters down with turrets. Words don’t really do it justice so here check out this video!
