In Singularity you'll face all manner of enemies throughout your mission including mercenaries and grotesque giant monsters. Weapons at your disposal include pistols, machine guns, rocket launchers, sniper rifles and shotguns. Each of these can be upgraded by collecting Weapon Upgrade cases located throughout the game.
Once you have found an upgrade, simply take it to a weapons station and use it to increase abilities such as clip size, reload times and damage. Alongside these, Singularity also features a number of unique weapons including a useful grenade launcher that allows you to fire off a round and target an enemy for maximum damage.
Another slick gun in your arsenal is the Seeker, a sniper rifle that lets you control the bullet once it has left the chamber. This weapon can be used to neutralize tough enemies at a distance, and for taking out foes hidden behind cover. However, Singularity's primary weapon is the Time Manipulation Device (TMD) that is attached to your arm at the outset of the game. This nifty gadget is powered by material called E-99, which is scattered in huge amounts around the island, so be sure to grab as much as you can to keep it fuelled.
The TMD can age, regenerate or levitate objects and fire a pulse of energy, and plays a hugely important role in solving certain puzzles you'll encounter over the course of your perilous mission. The TMD's powers can be applied to the mutants and soldiers you'll find lurking around the island too, so be sure to use it in combination with your firepower for maximum impact on the battlefield.
