I actually love packing Dummy rockets with 70 bucks worth of frag grenades or stick grenades and seeing how long I can hold out just smashing missiles into invading parties in skirmish mode. Dummy rockets are quite small and light, but pack the same engine power as the larger crafts so you can load them up with allot of stuff yet still fly them no problem.
You can also pack stick grenades into those carrier shuttles or whatever they're called, then you can perform bombing runs by flying overhead and just dropping the grenades. Stick grenades explode pretty easily on impact when dropped.
Crab Pots are also a fun variety to the crab mayhem.
Most of the mods I use only add bunker tiles right now. I'm not partial to most of the weapon or actor mods.
Yeah I'm looking for tile mods and maps mostly, I'll be waiting for the developers to make more actors and weapons.
