Build 251 is Now Live on Steam!

Posted by 11 years ago

Some builds just want to watch the world burn. Build 251 has been in the works for quite some time – Unlike the new heir to the British throne, it did not decide to arrive promptly. A build’s recalcitrance may be measured by Brian‘s quality of life. When Brian is at his post long into the night, making build after build, you know that it’s a tough one.

This is the nature of software development. Sometimes the intricacies, dependencies and complexities bite you in the ass. But today Build 251 is here, and it is glorious. Two particularly exciting new features are the ‘Cystem’ ¬†and queued orders. The Cystem is an auto cyst placement system that will chain link cysts to a destination for you.

Cystem – Four cysts to a res node in one click

Natural Selection 2 straddles the border between first person shooter and real time strategy (RTS) game. Most RTS games feature a queued order system, allowing a player to give several orders at once to be carried out in succession. Until Build 251, NS2 lacked such a system. This increased the cognitive and action load on commanders, as they had to actively manage player objectives as soon as objectives were reached. No longer!

The above example is quite simple, and involves just movement waypoints. The system is obviously much more useful when queuing movements with structure construction, attack, and other objectives.

Build 251 features a whole host of other features, fixes, and improvements. For example, shell ejection is back in (see below). There are also some balance changes hidden away in there.
