In this thread, I want to know what everyone's favorite tactic is, with or without mods.

My favorite tactics include the following:
1: Using the unitec mod, I like to make tf2 classes, such as scout (Baseball bat + dropship engine = explosions) and Heavy (Random chaingun)
2: Close combat. I like crushing enemies that have weapons when mine is gibbed/destroyed by an explosion. You can do this easily by jumping atop them, And gibbing their heads by sitting on them. You can jet towards them at high speeds, and sometimes that'll work if you duck while jetting at them.
3: Last but CERTAINLY not least, I enjoy the CRABBOMB. How to do this in a step-by-step format:

Brain unit against an onslaught of enemies.

Headshots.

Or shooting explosives at a body, making the whole actor EXPLODE.

Depends on my mood, but several of my favourites are:
- Grabbing a LMG and start spraying at waves and waves of incoming enemies
- Using only throwing knives to kill enemies (you'll be surprised how skilled you become)
- Having my brain exposed with the only defense being an actor with a sniper rifle, which needs a lot of headshots to keep up with the incoming stream of actors
- Using my moving brain actor in a game of 'survival', carrying a shotgun.

Using a single shot explosive launcher that lobs grenades to headshot enemies.

I honestly never get tired of that weapon.

I'll usually just place the brain in a closed tomb made of test material, but only when I'm too lazy to make a nice base. Otherwise, I'll use one actor with a ranged rifle, a pistol, and some grenades, and see how long he can last, or try to fend off DSTech robots in Lunar Tomato.

I usually just go solo with a very strong actor, and a brain in 360 Degree Protection.

But on mission maps, you just gotta remember that everything is destroyable and you
can destroy anything through the destroyed. Ex: Dig through ceiling, nab the brain Et Cetera

make barin un-destroyably sheilded, then enjoy a nice long game... untill it crashes

solid snake [eq]/naked snake + distance rifle + sidearm of your choice vs. darKlones, damn fun. that or one man armying vanilla stuff with a darKlone + shotgun

I like making a trap-filled base in Simple Mountain, then using relatively weak actors with vanilla/vanilla-balanced weapons to try and prevent my base's entrance from clogging with corpses.
Unitec + Promguns + Trickster Security ftw.
But that's not really a tactic. Tactic-wise, I like N.O.E. flying slow, as it is faster than walking yet keeps me close to cover. Also, even if I slam into something, it's likely to be an AHuman, not an ACDropship, so I can take down at least one more unit before blood loss kills me.
Other good tactic is having a unit with a digger and a GML destroy things from across the map.

I CHARGE MAH LAZZAH!!!

holy carp! thats pretty win.

Oh my god you didn't get it. * SHUN!!! *

PM me when you figure it out, but thanks for the win.

Foa you "did it wrong" yourself.

If you're going to spew something unoriginal at least make sure you're spewing the correct unoriginal bull♥♥♥♥.

First I build a giant base or use the only one I actually made. Position lots of stuff like defences and miners tactically. Then I play as the AI slowly eats all of my defences away and reaches the brain. I mostly use modded activities like zealotians or unitec or darklones.

Another game I play is having an unarmed Solid Snake on a complex base map and nothing else. I start the game and run for my life while trying to get a chance to pick up a gun the AI drops. And reach for a x number of kills until I suicide or get killed.
