so much q1sp releasing... it's craaazy!
terra5 i found annoyingly hard this time, but i think you were supposed to carry the weapons over? i kept loading each without weapons.
i liked the last one very much (6) because it was q1runic, although that trap was annoying and i only figured it out because when i died the first time, i could see through the func_door and discovered the trick. not really the coolest thing imo... :\
also, terra5 was a really nice looking (oldskool e1m2-e1m4 theme)map, but i couldn't figure out the trick to open the door at the end to finish the map (ended up noclipping through). i liked how you could see the way to the exit but the rock collapses at the start. :)
got the demos of the maps:
