An instruction is included within the game! Press space to skip the Intro Screen WASD or Arrow Keys to move, mouse to aim and shoot. number keys to change weapons. ~ Mobile device control available! Though, the feature is only experimental so it is very janky To change to mobile device control, go into settings and toggle it on. You can use the Settings button to change the graphics and difficulty
This is of course a "tweaked" version of half life standoff by @CaoLuan. Here is a list of all the tweaks so far: HECU marines have joined the fray. There are currently two variants, MP5 Marines and Shotgun marines. They will try to kill you, but they don't care if the zen creatures get in the way. On death, they drop ammo, small health kits and occasionally the weapon they were using. The shotgun has been buffed to do about considerably more damage because I felt it was slightly underpowered. The sounds for it have also been modified. Because of this its reload speed has been decreased. The bullet spread of the pistol has been decreased slightly because it was a bit "Spray and pray" before, but without the damage to compensate for it. The spawn chance of health and suit energy has been increased. The Gluon gun now uses ammo much more slowly Bullets are now longer (physically) to improve the slightly patchy hit registration of the vanilla version. Also funni chikin valv intro lol Planned tweaks: Making the end screen show you stats (eg shots fired, kills)
