When you have the invulnerability pick-up you can plow through the baddies with your suit. It's a great way to take out enemies quickly.
If you've already maxed out your weapons with your current character and you encounter another power-up, switch to one of the other Martians and let them pick it up.
As powerups are uncovered, distribute them to the BUMs that need them the most. You cannot exceed 6 powerups for weapons & defense.
Beginners may want to use 2-T (the blue one) since he has the strongest armor and will be able to take more damage before having his powersuit drained
If you do not have the MEC and need to avoid Stoat Muldoon, switch to B-Bop (the yellow one) until you can find the MEC since he’s the fastest.
