I have decided to highlight a, in my opinion, good mod every week. This week I have decided to highlight Stargate Mod by aVoN. I have always considered this mod to be among some of the best I have encountered for Garry's Mod, and many people have built upon what aVoN has done to make it even better. This mod includes new entities, such as the ring transporter and stargate, as well as new weapons.
In addition to the new entities and weapons, there are also NPCs and many tools added into a "Stargate" tab in the tools (Q) menu. This mod is extremely useful on spacebuild servers, as it makes travel to other planets easy for those who do not have a ship or do not want to build a ship.
When used in a combat situation, the offensive and defensive capabilities this mod brings to the table are astounding. Weapons can be mounted on anything and controlled by either wire, or by the use key (E). The weapons are extremely powerful and some can punch a hole clear through enemy spacecraft.
On the defensive side of things, there are a few options. First, there is the cloaking device, which makes an entire contraption or area invisible, and can also make it temporarily no collide while cloaked. The shield is also amazing, as it blocks most projectiles along with any prop, entity, or radiation damage (thinking nuke).
