A twin-stick shooter from Housemarque, Alienation sees you and up to three friends playing as a squad of soldiers trying to prevent an alien invasion. A split-screen option was patched in after it released.
Pro Lots of variety in enemy type
There are many enemy types, from the slow-moving kind you can simply shoot down as you run and gun, to ones that move fast, explode, wear heavy armor, and teleport around the map. Every enemy has a trick up it's sleeve, so you'll have to adjust your strategies on the fly. As you progress through the game, the enemies become more numerous and stronger resulting in exciting and balanced gameplay. You won't get bored of shooting the same enemies over and over, as they are randomly placed with plenty of variety.
Pro Fast paced, arcade action
The action never stops. Enemies of multiple types spawn all over the place in random locations, lasers and flamethrowers light up the screen, and things explode into a shower of color and particle effects. Loot is everywhere, drops randomly, and can be upgraded RPG style. There's hardly a chance to catch your breath because the enemies just don't stop coming as you make your way through procedurally-generated maps and missions.
Pro Great weapon looting and upgrade system
There's always a new weapon to loot or find via randomized weapon drops. Weapons come with a variety of upgrade sockets that can be fitted with upgrade "cores" to increase the base stats like damage, clip size, and rate of fire. All upgrades are incredibly satisfying as they feel immediately more powerful.
Each player can carry 3 weapons at the same time, as well as a grenade slot for explosives like boomerangs and mines. You're free to mix and match your weapons to create a style that works for you.
If you're not happy with your random drop, you can always salvage/reroll it to have new stats and sockets. Regardless of your weapon choice, you'll always be able to custom tailor it to suit your playstyle through the versatile upgrading system.
Pro Different classes to compliment each other in co-op play
Alienation features three different classes to choose from, all of which compliment each other in co-op play. Tanks can take the brunt of the damage, while saboteurs can dash into swarms of ranged enemies to take them out, and the bio-specialist which serves as an assist role by healing teammates can unleash clouds of poison to choke enemies. Playing with your friends offers the opportunity to create some fun team compositions that compliment each other as you work together to blast your way through swarms of aliens.
Con PvP can be unfair
Through an 'Invasion' system, other players can invade your game and attempt to kill you while you attempt to defend against them. However, there is no attempt to match up players of equal power, so it usually results in unfair play where higher level players are demolishing lower level players. It feels very unbalanced and offers no extra rewards like loot or experience.
