New Conglomerate Starting Guide

Some quick Tips:
E - enter/exit vehicle, use terminal
F - Uses special power, aka shielding/cloak
Grenades - stock up grenades at infantry terminal (the gun icon) or switch to MAX (mecha)

Your goal at the beginning is to get into the thick of things, find where the action is and starting killing shit.  You can press M and click on a battle icon to hot drop in, or you can grab a vehicle and head over there.  Once in an area you can spawn at nearby locations, to get back into the action ASAP.

Infantry Classes:
Heavy Assault, the (f) shield lets you take more punishment and win most head to head fights.  Your Gauss Saw is decent in burst fire for medium range, and full auto for short range.  Always stock up on grenades, and throw them out at the start of a fight, or even towards the enemy.

You can switch to rocket launcher to wittle down tanks/vehicles/turrets or fire into doorways when assaulting into urban environments.

Cert upgrades for HA:
Resist Shield (High Priority): This is a huge boost to survival, right now it's by far the best activated ability.  Upgrade it to lvl  1 asap.
Grenade Throwing power/quickness (up to lvl 2 each asap): These are universal upgrades and grenades are really powerful.
Gauss Saw Attachments (High Priority):  Get forward grip and unlock scopes/compressors etc to increase accuracy or hide your indicator while firing.  Really good boosts.
Grenade Bangolier (mid priority): Get 2-3 grenades per spawn instead of 1.
Upgraded Rocket Launcher (Low-mid): Just upgrade your rocket launcher at some point, not high priority but it will help you out a bit.

VEhicles:
Not an expert here, but upgrade these after essential infantry.

HE turrets are really good anti infantry.

Air sucks ass right now.
