Yea NS1 is actually better. I'm looking to see if its gonna be a good game before I buy it off steam, cuz the latest alpha had lots of bugs (bad lag compensation, bad hitboxes on alien models, barely anything in it, etc.).
The engine is really easy to hack also, model rec takes about 5 seconds. Its just that they only have like 2 marine models, and2 alien lifeform types so far.
