Jet/shottie Rush

Licho

<div class="IPBDescription">easy way to quickly kill hive</div> Since shotgun damage vs. building is not halved as damage from hmg, hive can be killed with ccca 40 slugs from shotgun (you still have 20 more to kill skulks). So 2 jetpackers can kill hive with single reaload. If you can fly you can always land on hive outside range of OC and kill hive before help arrives. This tactics is widely used on our server and in some games aliens just weren't able to stop such jetpacker unless using ridiculous number of OC and webs around.
Oh and btw, jet/shottie now costs less than previous jet/hmg.

I tried this earlier today when I got into the command chair half-way into the game. Marines were losing because the previous commander did a poor job in utilizing resources. However, I did manage to offer very strong resistance and they struggled even though they had three hives. Unfortunately they pretty much most of the map covered, so it was a lost cause. SO in a last effort, I decided to test this strategy out - and managed to take down all three hives in the span of 5 minutes. Of course, I was nearly broke and the Kharaa just put the hives back up. It was a good demonstration though.

Even better, 3 guys with JP/shotty and l3 weapons can take down a hive in 5 seconds!

It's a shame that the proto lab requires adv. armoury 'cos otherwise I would never upgrade the armoury. Shotties are too good with HA/JP.

LA/shotty is less effective as you have neither the maneuvrability nor toughness to get close enough to attack.

Don't underestimate LA/shotties. The entire idea of shotty attacks is to be a surprise... I won't go into how you can perform LA/shotty rushes, since I'm now holding that as a trump card (it's now pulled me out of two games I fubared early on). However, yes, the fact that hives can go down before aliens realize they're under attack is... sick. And very useful.
