This is a small guide simply designed as a catalogue of tips and tricks that I have found while experimenting with the game. I will add more things as I go along and discover more. Some of these things will be obscure and some will be very obvious, but I aim to teach everyone at least one thing. If you have anything that's not in the guide, feel free to comment it down at the end and I will add it with the appropriate credits.

The contents of this list are in no particular order. I may organize them as more are added, but for now there is not enough content.

Some of the contents of this guide are outdated, and I will fix them as soon as I can. I currently don't have the game downloaded but will do it soon and get back into this.

• You can use gun pushback to propel yourself backwards or upwards. I use it to get to secrets up high or away from groups of enemies. Jumping while firing down can boost you even further, and more guns increases the effect. Thanks to mackintosh12748 for this info!
  
  
• It is possible to have negative pushback, such that firing your guns will move you forward. As far as I have seen, M-29 Forward Booster caps are the only module capable of reducing pushback. I have been told that there are several caps capable of reducing pushback. Thanks again mackintosh12748!
  
  
• There is an inventory cap. You can have a maximum of 100 equipment pieces in your global inventory. This can be increased by purchasing inventory expansions from the smuggler.
  
  
• Secrets are incredibly common. There is nearly one in every room (possibly more? sometimes more). Look around often for the glowing secret indicator on the wall panels. Secrets are often on empty wall pieces, but not always flat ones. Sometimes they may be embedded behind ramps or other set pieces or on top of higher areas in the room. I learned some of this information from CrazyGunMan102's guide, found here.
  
  
• Energy recharges marginally slower when you drain it completely. I will test this more.
